Dear friends:
I have done a simulation on cpw-fed antenna. The project is attached below, and the result have come out. But I am not sure that the resultant is right or not. Please experts check it for me. In this project, is the resonant frequency 2.86GHz(Fig.1), and is the impedance at resonance frequency 0.15ohm(Fig.2)? And why is the frequency corresponding to 0.15ohm 2.62GHz, different from 2.86Ghz corresponding to the lowest point in the plot of S11 against frequency.

Re: Please help me decide hfss cpw-fed antenna simulation re

that's a good question. i'm not sure, but if i was you then i would do a discrete sweep around the resonant frequency and then check S11 and the impedance...

:D Thanks everybody! I forgot to assign a material to the monopole, so now it has been solved.
