Can anyone upload a working simple microstrip-fed slot antenna design file in HFSS. I have been trying to simulate one for months, but I only get an unacceptable radiation efficiency of more than 1.0 and and unrealistic gain of 5dB. Please help me!:???::???:
PS: 2.4Ghz antenna, if possible.
Please everyone,
I am trying to simulate a simple slot antenna in HFSS, but the gain for my antenna(~6db) far exceeds what was stipulated by theory(~2dB). Worse still, the radiation efficiency is more than 100%!! Could anyone kindly check out my attached simulation file, and please tell me...
@ferdows
I am posting a new thread because u are not giving me specific answers. Give me the numbers. When you tried to simulate my antenna with CST/HFSS, what gain and radiation efficiency did you get? A simulated efficiency of more than 100%, does that look normal, paper or no paper. And by...

@ferdows
What radiation efficiency and gain did you get when you simulated? I am getting an efficiency of more than 100% with HFSS. That cannot be true.
Thank you.
@ferdwos
Did you check the gain and radiation efficiency of my antenna? The gain is far more than the normal 2.15dB of slot antenna. And the radiation efficiency more than 1. That is my problem.
Thanks

Hey everyone,
Please, I would like to design a simple slot antenna with FEKO.
My specification:
A thin rectangular slot of half wavelength is to be cut on a finite conductivity, finite size ground plane. The slot antenna is to be fed by a microstrip line on a substrate.
Can anyone upload a...
Hi, everyone
I am using HFSS to design a microstrip fed slot antenna on a finite ground plane at 5GHz. When my ground plane is 50mm x 50mm, I get reasonable gain pattern. However, increasing the ground plane to something bigger distorts the radiation pattern especially at boresight. Further...
Hey peeps,
Trying to do this has consumed so much of my time.
Can anyone explain to me how best to feed a slot antenna with a coaxial transmission line, and how to investigate the correctness of the design.
Thanks in advance
