Hello,
Indeed, i am working on UHF tag antenna and i simulat them using HFSS simulator. For excitation, i put a 50 Ohm lumped port ( idont know if is it good or false) but what i have difficulty understanding how can i extract the internal impedance of the antenna. In another, mean, did the fact to have a port of 50 Ohm can disturb the internal impedance of the antenna and thus get a wrong answer? or i must to put the impedance of the microchip and then adapt the antenna? please help me
