868 915 MHz Antennas

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.

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.

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.
