[Joe_Qiao]

Now I doing a project with nRF52810, How to design the PCB Antenna of nRF52810? Can you give me a example?

Hi, you can find the reference design here: https://infocenter.nordicsemi.com/topic/ps_nrf52810/ref_circuitry.html?cp=4_4_0_6_2_8#layout

The reference design is part of the nRF52 DK, and the Altium or Gerber files can be found here: https://www.nordicsemi.com/-/media/Software-and-other-downloads/Dev-Kits/nRF52-DK/nRF52-Development-Kit---Hardware-files-1_2_1.zip

Here's a document on antenna tuning: https://infocenter.nordicsemi.com/pdf/nwp_017.pdf?cp=14_12
