patch array

Hi guys,

now I am working on attached design but simulations shows me a better match impedance for 2.2 GHz and laboratory tests showed me a better match impedance near 2.56 GHz some weeks before. Could someone revise my project in order to find mistakes?

I am self-learning about ADS.

Also, all my work is published in internet under Team FREDNET project (www.teamfrednet.com - Wiki - PicoSAR). You can see it and contribute!

You need to do EM simulation.

Thanks for your reply. I did it, obtaining best match impedance near 2.3 GHz. If you want I can send you EM simulation.

Enric.

Then please send it

Thanks a lot,

Enric.


PD: some pictures showing differences results (laboratory, ADS)

More info

I observed that the antenna is replaced with transmission line and is not the correct way.
