reduced mutual coupling

hi
i research about reduced mutual coupling between two patch antenna
i do not know how define two coaxial feed in HFSS
if possible can say how to do the two rectangular patches on single substrate and give the coaxial feed

Hey ,Once I did exactly what you want in HFSS (reducing mutual coupling), but I never used coaxial feed, You can go through some other ideas I really did; if you get upset with coaxial feed, I may give a help.

Hi,

You can find an example of Patch Antenna Design with Coaxial Feed in the HFSS (Online) Help. By the way, you can easily define the two feeds by using two coaxial probes, one for each patch antenna. Then you will have two excitations, one for each coaxial probe.

Let me know if you still have some trouble. Regards,
