How can I see the Radiation Pattern in different direction in HFSS

I have designed a Patch antenna for 2.6 GHz. Now I have place two same type antenna in 90 degree direction from each other. I want to see the resultant radiation pattern in HFSS. but everytime I simulate and try to see the radiation pattern, it show mostly in one direction with the effect of other one. I tried array (custom and fixed array) but didnt work tht well. Can anyone give me a solution?

I'm not 100% sure if this is the issue, but have you specified both ports to be active? (right click field overlays, edit sources).
