LoRa LPWAN IoT Antennas four hot products

LoRa LPWAN IoT Antennas are a hot topic right now and building out a reliable network based on 868 MHz or 915 MHz requires the deployment of quality antennas and accessories. Here we look at four robust antenna types to facilitate consistent and dependable installation.

High gain outdoor omni-directional antenna

On the edges of the network where signal strength cannot always be depended on, a quality outdoor antenna is often a go to solution. Common requirements for such antennna are be robust with the antenna and bracket built from quality components, offer high gain (5 dBi+) to provide a stable signal, be compact enough to be discreet and offer flexible mounting options. Combining these factors will deliver consistent performance whatever the climate conditions. A fine example of such an antenna is the WMO86916.

Wall-mount omni-directional antenna

Some external LoRA LPWAN IoT antennas are required because the antenna cannot, for one reason or another, be mounted directly onto the radio. For reasons of signal coverage, location of radio/terminal below ground or in a shielded area, willful damage or simply practicality, wall-mounted omni-directional antennas are often used. For most applications they need to be compact, discreet and cost-effective while offering robust RF performance. They also need to be easy to install in order to keep installation costs/time to minimum. Two excellent choices of such antennas are the Wall-Blade and the WCO-868-WMB. Both are very compact, easy to install and offer accomplished RF performance.

Low profile permanent mount puck antenna

Antennas are often required to mount directly onto a terminal or enclosure. Mostly permanently mounted by a threaded boss through which the cable is fed, they offer a secure and effective way to facilitate 868 MHz and 915 MHz communications. Such antennas need to be very compact with a durable radome, be of a material to withstand inclement weather, possess a durable mounting stud and offer reliable RF performance. Many of the small pucks, smaller means that they less likely to draw attention to themselves, are groundplane dependent i.e. they have to be mounted onto a metal surface. One such antenna is the Button 868 915 MHz antenna. This antenna is compact as it gets without compromising on RF performance.

Terminal/Radio-mounted dipole antenna

In cases where the antenna does not need to be mounted away from the radio or terminal, a dipole antenna can offer reliable RF performance when directly connected via a coaxial connector. This type of antenna is not the smallest, you can find small 1/4 wave antennas that are much more discreet, but they typically offer robust RF capabilities. Especially where no groundplane is available, for example if the terminal has a non-metal enclosure, the dipole style antenna can offer RF advantages over rival terminal antennas. In addition, do verify the build quality of such antenna so that you can be assured that it is built to last as inferior antennas can be very easily damaged thereby demanding costly engineer revisits. A good example of a quality dipole antenna is the BKR915 and the BKR868.

Aside from the antennas, it is wise to make sure that if you are running coaxial extension cables you use quality cables to minimise cable losses. At 868 MHz and 915 MHz for cable runs up to 10M, you could typically use RF195 type cable. From 10-20M it would be worth considering RF240. And for longer RF400 cable installations. Using inferior coaxial cable will negate the benefits of use quality antennas as signal losses across the inferior cables will be experienced.

Some of the antennas mentioned can be purchased via the Connex webshop.

868 915 MHz Antennas offer new options for connectivity

Two new 868 915 MHz antennas from EAD offer more choices for connectivity in 868 MHz and 915 MHz applications. Addressing deployments such as LoRa, Sigfox and other unlicensed frequency band systems, the Button 868/915 and the Wall-Blade offer designers and installers more flexibility when rolling out wireless systems.

The Button 868/915 antenna is a compact low profile puck antenna designed to be mounted onto a groundplane (i.e. metal surface) such as a cabinet, enclosure, kiosk or roof. Permanently mounted via a threaded stud underneath, the antenna is fed by a single cable and supports both 868 MHz and 915 MHz frequencies. It measures just 62.7mm in diameter and 27.5mm in height and offers a robust, discreet solution for modems, gateways and access devices where an antenna needs to be mounted externally.

The Wall-Blade antenna is an effective wall-mounted blade antenna for 868 and 915 MHz with small dimensions to enable unobtrusive installation either indoors or outdoors as required. It is supplied with bracket and fixtures for mounting and is fed by a 3M cable and SMA-Male as standard. The Wall-Blade offers reliable and consistent performance in both bands and is an innovative alternative to standard tube-style omni-directional antennas.

For more information on these antennas and other solutions we offer for 868 MHz and 915 MHz, please visit our product catalogues.

For European customers some EAD 868 and 915 MHz antennas can be purchased via the Connex webshop.

Button 868 915 MHz Low Profile Puck Antenna

The Button 868 915 MHz compact low profile antenna is a discreet screw-mounted puck antenna. Supporting 868 MHz and 915 MHz frequencies, this robust antenna is mounted via a 14mm mounting hole for permanent mounting. Measuring just 62.5mm in diameter and 27.5mm in height, the Button 868 915 MHz compact antenna is one of the smallest low profile ISM band antennas on the market. The Button 868 915 Mhz antenna when mounted securely onto a flat metal surface is waterproof rated to IP67.

This antenna is ideal for LoRA and licence-free applications such as wireless security, vending and retail kiosks as well as access applications where a small permanently mounted antenna is required.

Various cable and connector options can be configured. Typical connectors include SMA, FME, CRC9, TS9, MCX and MMCX.

868 MHz LoRa antennas – a selection guide

868 MHz LoRa antennas are becoming a hot topic in our markets. Using the licence-free ISM frequency bands, LoRa is a long range, but low power wireless technology that is increasingly being used for IoT technology. By wirelessly enabling devices and terminals to operate using LoRa technology, applications can be developed for control and monitoring without the need to use mobile cellular networks such as GSM, 3G or LTE. All of the LoRA enabled nodes will need an antenna of some description and here we look at some options to help enable your 868 MHz IoT environment.

There are many choices of 868 MHz LoRa antennas, but we’ll focus on internal, terminal mount and outdoor omni antennas to cover requirements for remote devices and hub/concentrator applications.

In areas of low signal or for concentrator applications where a higher gain antenna is required, an outdoor omni antenna is often a good choice. Especially if you can select an antenna with good gain figures, the nature of an omni-directional antenna in radiating in a 360 degree pattern allows communication with other devices and hubs in every direction. These outdoor antennas can be wall or pole mounted and can be supplied with various levels of gain depending on the antenna size – see the DMO8684 for a 4.3 dBi gain in a compact package or the WMO86916 for a 5.8 dBi gain version which is a bit larger.

For external mount antennas where the following terminal antennas cannot be deployed, sometime a compact wall-mount antenna offers a useful alternative. Perhaps the radio is housed in a metal enclosure or a cabinet and a terminal antenna will not fit directly onto it. An antenna like the Wall-Blade which has a small footprint might well solve the problem.

For terminal mount antennas i.e. antennas that mount directly onto the device or terminal, typically you can go with a small stub antenna like the WS868 and the MW868 or a dipole style antenna similar to the BKR868 or HWD868. The stub antennas are smaller, however usually offer lower performance than the longer whip or dipole antennas. The selection of the terminal antenna depends on the environment in terms of space available and the desired performance. Captive mount terminal antennas are also possible where the antenna is locked in placed with a nut so it cannot be removed and the antenna is connected via an integrated coaxial cable and connector – for an example see the W868-FLY.

For internal mount antennas, a simple solution is a groundplane independent PCB such as the IoTa or  Morava antenna. These antenna mount inside a non-metal enclosure or terminal housing with a minimum of 15mm clearance from any metal components or surfaces and can provide a discreet way of enabling 868 MHz communications without the need for external antennas.

Hopefully the above information has given you some food for thought about possible LoRa antenna solutions and offered some suggestions on how to enable antenna solutions with your application. For customers not using 868 MHz, for example in the USA or New Zealand, many of the above antennas can be re-tuned for 915 MHz if required or have 915 MHz options.

For customers in Europe, the some of these antennas including the WMO86916, DMO8684 and IoTA can be purchased via the Connex webshop. For other questions, requests and quotes for 868 MHz LoRa antennas, please feel free to contact us.

Four interesting antenna solutions for 868 MHz

We take a look at some interesting antenna solutions for 868 MHz that might be used for LoRA or Sigfox applications. 868 MHz in many parts of the world is a licence-free frequency band. Increasingly this frequency band is being used for IoT networks for longer range access for data applications. That being said no one antenna is suitable for every application, therefore many customers need to consider what mounting option is required and where best to position the antenna when designing an installation. Here are four suggestions:

868 MHz multi-position dipole antenna

For fixed and mobile terminals where the orientation of the device is not always certain, sometimes it helps to consider a multi-position antenna where the antenna can be moved from the horizontal to the vertical position. Terminated with a coaxial connector such as SMA, RP-SMA or TNC for example, the antenna element can be lock in three places depending on the installation.

868 MHz captive-mount monopole antenna

For applications where you would need a small quarter-wave antenna, but want to discourage the removal of the antenna from the application, you could consider a captive mount model. This means that the base of the antenna is mounted through the terminal’s metal enclosure and held in place by a locking nut. A coaxial cable feeds from the bottom of the antenna through the mounting boss and can connect to the radio module.

High gain 868 MHz outdoor omni antenna

For fringe areas of signal, a 5-6 dBi outdoor omni-directional might be useful. Wall-mounted and supplied with a 5M cable to connect to the radio or device some way away, this high gain antenna can often aid reception in difficult installations. Fully weatherproof with a fibreglass tube, this antenna can be mounted outdoors permanently.

Internal 868 MHz PCB dipole antenna

A half-wave groundplane independent PCB antenna, this enables the antenna to be installed inside a non-metal terminal enclosure enabling a discreet, but functional antenna installation. Various cable and connector options are possible including U.FL, MMCX and SMA.

This list of antenna solutions for 868 MHz is not exhaustive so if you cannot what you need here, please feel free to e-mail us or use our antenna configurator.

WS868 – 868 MHz quarter wave stub antenna ST

In addition, across this line of products we have 433 MHz and quad band cellular models available.

 

WR868 – 868 MHz 1/4 wave stub antenna RA

The WR868 is a 868 MHz 1/4 wave stub antenna RA designed for ISM band terminals. Requiring a groundplane to operate a effectively, the WR868 is a based on a helical coil design and offers a compact solution for fixed and mobile terminals need 868 MHz connectivity. The antenna element  is housed in a durable and robust black acetal sheath.

As standard supplied with a SMA-Male right angle connector, a version with a right angle RP-SMA plug is also available.

Also available is the WS868 which is a straight SMA-Male version of this 868 MHz stub antenna.

In addition, across this line of products we have 433 MHz and quad band cellular models available.

W868-FLY – 868 MHz captive mount whip antenna

The W868-FLY is a 868 MHz captive mount whip antenna based on a 1/4 wave whip design requiring a groundplane operate optimally. Ideal for fixed and mobile 868 MHz ISM band terminals, the W868-FLY antenna is mounted via a threaded stud and held in place but a locking nut. This captive-mount mechanism ensures that the antenna cannot be easily detached from the terminal thereby discouraging wilful or accidental removal of the antenna from the application.

The W868-FLY is housed in a flexible injection-moulded sheath and typically is supplied with approximately 215mm RG174 cable and is not terminated with a connector. Connectors can be terminated if required, but ensuring that the connector is not larger in diameter than the mounting stud. Therefore connectors such as IPEX, U.FL, MMCX and MCX make good choices for this antenna.

For a SMA-Male based 1/4 wave 868 MHz whip antenna, you could consider the MW868 antenna.

A 915 MHz version is available subject to a minimum order quantity.

BKR868 – 1/2 Wave 868 MHz dipole antenna

The BKR868 is an 868 MHz dipole antenna, 1/2 wave and groundplane independent, designed for ISM-Band terminals and devices that do not have a groundplane or metal surface on which to mount a 1/4 wave antenna.

Housed in a durable sheath, the BKR868 has a multi-position SMA-Male connector that allows the antenna to operate in a horizontal or vertical position. This makes it suitable for portable devices where the orientation of the product is subject to change or is not known.

With a VSWR of less than 2:1 and a gain of 2 dBi, the BKR868 is an effective antenna solution for a range of 868 MHz ISM band applications.

The formal part code for this antenna is FBKR35300-SM-KR.

A 915 MHz version of this antenna is available called the BKR915.
