can you please explain clearly, my friend? impedance value of chip is 36-j750 Ohm. when I use stub to impedance matching but input impedance of antenna just increases about 10+j250 Ohm.
more than, I must obtain broadband from 860-960 MHz. please help me! thanks very much!
Thank you very much! I am researching that. By the way, could you please help me about:
"I have a RFID dipole antenna (microstip line), I want to measure input impedance and return loss so that I compare with simulating. But I don't know anyway. Could you please help me?" Thank you in advance!
