I'm developing my own board featuring the nRF5340.
I wanted to add a PCB antenna to my layout and I figured the fastest way to create a functional prototype is to copy the nRF5340 DK antenna.
So I just wanted to have some confirmations before going all in:
- Is the matching circuit chip side ok? Do I need to consider any other PCB specifications?
- Is it ok if the RF trace is different from the DK, but matches the 50 ohm anyway?
- I wanted to place a 0 Ohm Resistor instead of the J1 antenna connector. Is it a problem? This way I can have different trace constraints for the RF trace and the ANTENNA trace
- If in the future we realize that the antenna doesn't work (either with the DK design or with a custom design), is it possible to have the board revised directly form the Nordicsemi team?
All the best,
