Hi all!
I've designed a wideband microstrip p atch antenna (~50 % !!!),using the cst Microwave.
However ,it has a poor performance according to the |S(2,1)|dB plot.
This is due to the coupling between the two ports.In order to solve this problem ,I've tried to enlarge the distance between the ports,but then the |S(1,1)|dB was decreased sharply.
Any suggestions how can I get over this problem?
Thanks in advance,
