nRF52833 any recommendation for chip antenna?

[Roveniki]

Hello,

I am looking for chip antenna 2.4 GHz any recommendation (Thread commutation)? 

[Andreas]

Hi,

 

We recommend using one that is suited and designed for use in a similar position and alignment on the PCB as you have planned. This is usually shown in the datasheet of the respective part. Not replicating the required/recommended mounting considerations will reduce the performance.

 

Best regards,

Thanks for answer, could you also help about bandwidth of antenna in relationship with data rate?  I want to use 2.4 GHz proprietary 2 Mbps how big bandwidth of antenna is necessary? Any recommendation?

[Andreas]

Hi,

 

Bandwidth as in datarate (1Mbps/2Mbps) is not really relevant. You need to look at the bandwidth as in the in-band frequency of the antenna. This might differ between your application and the protocol you plan to use, BLE and Thread as an example should have antennas that support 2402MHz-2480 MHz.

 

Best regards,

Andreas

Hello Andreas, thank you very much. I was looking for relationship between datarate and bandwidth of antenna but what you wrote makes sense it depends on protocol. Thanks again
