Hello Mgscasso,Matching this antenna:Inside the datasheet you can find the antenna parameter in free air. If you don't have a VNA, this is a good starting point for you. There is no parallel resistance at resonance frequency state, but i think you ca...
Hello Ricko, There are no general or universal values you can input into the antenna matching tool.Those inputs are specific to your antenna. On a differently manufactured PCB, e.g. different layer stack, different dielectric parameter, the antennas ...
Hello Dejan, Although the same antenna is being used, the matching could be different due to parasitic's.This could originated by using a different PCB layer stack.Therefore i would recommend to verify first the smith chart using a VNA.Afterwards we ...
Hello Rezan, which standard are you testing against?I am not familiar with any standard (FCC, CE/RED, CISPR) measuring in µW.Here you can find measurement results of the NFC03A1.https://fccid.io/YCPNFC03A1Please let me also know your measurement conf...
