Patch antenna simulation - help needed

how a patch antenna works

Hi all!
I'm new with simulation and antenna design. I'm triying to simulate a probe-fed rectangular patch antenna on a finite ground plane.
I designed this antenna by transmission line model using fiberglass as dielectric substrate with Er=4.4 and h=1.52mm.
The size of this patch is L=29.47mm and W=38.03mm. The size of the ground plane is Lg=38.59mm and Wg=47.15mm.
I tried to simulate this antenna, but i cannot get it to work... Please! If someone could give some feedback and help me I would be very grateful.
I added my .geo file and a description of all the steps i followed using IE3D.
Thanks a lot.

microwave antenna simulation for 2.4ghz

would u mind if i simulate your structure in hfss and give u the input.if so let me know what is your operating frequency.


i am assuming it to be 6 GHZ.

patch antenna simulation project

Hi Sajid.
The operating frequency of my design is 2.4 Ghz.
Please it would be nice if you could tell me if it works in hfss!

Thank you!
Regards

patch antenne simulation

I am doing a antenna of similar caracteristics like your antenna for 2.4 GHz and works relatively well. Follow www.emtalk.com, here I found some help.

I posted a project for a single patch simulation at 2.5 GHz with HFSS.
