antenna design for rfid tags
hi,
For future work, first I want to replicate the simulation presented in document 1, but I can not find the same results. I put the port of excitation between the antenna and the tag, but the results are not the same. I think the problem lies in the position of the port. but how do I fix it? I also kept 50ohms impedance for the port.
1- document where the antenna is illustrate (Fig1. Design architecture of the antenna)
2- image of tag antenna and my designe with cst!
thank you in advance for your assistance
