Hi Bill John,
Thanks a lot for your reply.
What are the good practices should follow for routing the traces from TX /RX IC to the coil ?
1) Thick and short traces ?
2) No via is allowed on the traces ? (will affect inductance if via added)
If the requirement on the PCB layout for the those traces cannot be fulfill due to size constraint, will it detune the coil resonance frequency?
If yes, then how to tune back the matching frequency?
