Hi all,

I have a problem when finished the simulation of patch antenna, please help me to verify results and verify the set-up if it is possible. The principe lope seems that do not in the direction vertical (with the patch plan), and the result has two lopes? I don't know why? I would like to have and I think that the patch can produces a smooth, symmetric pattern with little backward radiation...(I will still develope but now it is important to find a solution for problem above)

I will appreciate all your help... THANKS very much.

Hi cuongtran;
İ looked at your simulation. i think the patch is so far from the ground plane. because of this, it has two main lobe.

Hi asondas, I tryed to change the distance between patch and GND for smaller but the results is not better, I 'll play with the substrate thickness..
