LoRa LPWAN IoT Antennas

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 MHz LoRa antennas

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.
