Hmmm..... Looks like another good incentive to upgrade to DXP ;) Too bad the main flow here is toward Pads...
But here are my 2 cents on PCB RFID loop antennas (at the risk of stating the obvious): 1) keep track on the parasitic capacitance in order to get it reproducable accross batches. 2) keep track of the L/C ratio in order to get the desired impedance. 3) keep track of the loaded Q in order to get the desired bandwith. Any more tips and I would be in violation of my contract.....
