As a bending increase so that the radius of bending decrease the effective length reduced (not increase , sorry for my mistake) sothe frequency should shift up and not down as in my case.

Hello,

I have designed a dual polarization antenna ( patch= copper, ground= copper, substrate= RT Duroid 5880) and resonant frequency f=2,443GHz. Then I bend it at radius=200mm and the resonant fre ...

Thanks a lot for your info.

Actually I am using the transient solver and as I mentioned above the number of cells is huge, I tried your idea about taking the volume symetry but again the number of ...

Hello,

I have to bend a patch antenna in the human body.
The human body will be implemnented by a body tissue simulating liquid with er=52.7 and conduct=1.95.
So I made a cylinder in CST using th ...

Thanks a lot for your quick reply!!!

Can you please let me know how can I achieve a good isolation in a square patch with 2 ports?

Please I need a rough idea about the scheme and then I will sim ...
