Where to find information about the built in antenna for the nRF54L15DK

[Gush9]

Hello,

i recently received several nRF54L15DK kits. 

The example good for channel sounding works well but left us with a question about the BLE antenna.

According to the product page, there is a built in antenna but no specific information is given.

Since we are planning on running some tests, we want to know every variable.

Is the built in antenna a pcb antenna (trace next to connector)?

Is an external antenna required for accuracy?

We read somewhere the external antenna allows for spectral analysis but we are unclear if it should also be used for normal use.

Is there a page i missed where more information is given about these things?

The antenna on the DK is a PCB strip antenna. You can find the design files on the Nordic website under the product page for the DK.

You don't need any other antenna to do Channel Sounding.

The accuracy is primarily impacted by the algorithm and as descrived in the Channel Sampling sample documentation, the algorithm in the sample is not designed for accuracy, it is only there to show data flow from the radio to the application code.

Hi paka,

I would like to ask if there are any related test files for PCB antenna field pattern testing on the nRF54L15DK, such as antenna pattern?

Thank you!
