Bluetooth Antenna Design

Bluetooth is a 2.4GHz frequency band used widely to transfer audio and data. In many applications, where there is a Wi-Fi antenna, it is shared with Bluetooth, and a dedicated Bluetooth antenna design is not needed.

However, many devices and sensors use a low-power version of Bluetooth (BLE), which benefits from higher antenna performance in terms of battery life. Another feature of the Bluetooth antenna is the price. Bluetooth devices are usually very price sensitive and benefit greatly from PCB trace solutions where BOM is driven to the absolute minimum.

With the introduction of Bluetooth 5 came mesh and long-range functionality. Mesh allows Bluetooth devices to connect and create links forward. A great feature but mesh functionality does not have an impact on the antenna design. The improved sensitivity and higher transmit power that enables longer range for Bluetooth 5 to affect antenna perspective. It creates another incentive like an IoT antenna where a range needs to be maximized, and the antenna needs to be optimal.

CoreIoT Services for Bluetooth 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 accurate performance forecasts in the early stages of development, enabling informed decisions before 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!
