https://devzone.nordicsemi.com/f/nordic-q-a/89042/nrf52832---antenna-finetuning-via-softwareHi, I am using a ISP3010 SiP which inludes a nrf52832, a DW1000 and the corresponding antennas (built-in antenna). I have a custom board (board1) as reference, where the RF-performance, especially the range of BLE and UWB, is pretty good.

We are at the same problem as you are! We are also potting our NRF board and for the reason, we are seeing shift of around 60-65 MHz. I dont see any solution with software, so its better to resort to tuning in hardware if you have multiple boards, pot them and check for the desired center frequency. Maybe you can use some field solvers to simulate your pi network for the desired impedance.</p><div style="clear:both;"></div>
