Hello,

i want to design a UHF RFID tag antenna, before i arrive to this step, I wanted to replicate the simulation presented in the attached paper, i used the same parameters as mentionned in the paper, but i didn't get the same results, i'm getting a low adaptation level and a resonant in a different frequency, i can't identify where is the problem, can anyone help please?!!

I have the same problem, if you found the solution, can you help me please
 

Hello Ali & Hocine

Most probably the matching between chip and tag input impedance... Anyway, if you would like to check your .cst file, please share it with me in order to validate it.

Thank you
