problem in coaxial port

[asmat ara]

hii, i am using bent type antenna but when i try to give waveguide port to my coaxial feed it shows not in plane . please help in this matter

Make sure your coaxial inner conductor is properly touching the feed region. If there’s a gap, the port may not recognize a valid excitation region.

thank you for the reply. The feed is correct, but when I apply waveguide port to it, it shows the picked face is not in any defined plane .

Thanks a lot . But the main problem is i have designed a bended antenna and the coaxial feed is creating a bit issue because of the curvature of the antenna
