IoT Antenna Design



What makes IoT devices different from an antenna design perspective?

In IoT connected devices, antenna design is more important than ever. IoT devices can be found in any kind of location. Quite often devices are in remote places, far away from communication infrastructure, and hard to access. This leads to 3 common characteristics:

1. Challenging communication environment 2. Maintenance free 3. Durability
Devices needs to be able to communicate with infrastructure that is either far away or obstructed by concrete, walls, or ground. This means that connectivity is often the limiting factor on who can use the device and any improvement on the communication range can help you to serve more customers. Because the devices are in locations that are hard to reach cost of any maintenance activity would be very significant. Therefore, any battery powered device should aim for several years if not for decades of battery life. Among other things, reducing the amount of data transmission and power needed for the transmission help to prolong the maintenance period. Many applications and locations where IoT devices are being used are such that the device needs to endure harsh environment from temperature, moisture, and mechanical stress. On the other hand, some locations are prone to explosions such as ATEX spaces found in places where gas, oil or other flammable compounds are handled. Solutions might be use of potting material, metallic structures or for example, size reduction. Solutions to these durability challenges are hazardous for wireless communication.

Common nominator for the three characteristics above is the pressure those place on wireless performance and antenna design. There are many technologies that have been developed to tackle the performance requirements and they fall under the category of Low Power Wide Area Networks (LPWAN). However, selecting a suitable technology is not enough. Even the best system and best product can fail if it has poor a antenna design.

CoreIoT Services for IoT antenna design

We offer antenna design services for full product development projects, from feasibility studies through different design stages to consultancy at the mass production phase.

Our antenna simulations are critical at reaching an accurate performance forecast in the early stages of development. This helps enable informed decisions before the manufacturing prototypes. Simulation enables us to use our extensive know-how in product integration to find new innovative antenna solutions.

We can measure TRP in an anechoic chamber when your device has been configured to transmit carrier wave signal (CWS) at maximum power. This means that our power meter will test the transmitted power in each direction, and results are integrated to generate the combined total power.
We specialize in high performance integrated solutions that are cost-driven. Check our references!
