Who ever simulated a horn antenna?

can someone help me about the dimension of rectangular waveguide and the place of coaxial line in horn antenna at X band fereqency for achieving minimum vswr.
i simulated at 10.3Ghz and G=20dB
PLZZZZZZZZZZZ someone help me.

Why don't you do a parametric study to find the best feeder position?

The best position (impedance matching wise) depends on various parameters, such as waveguide dimensions (height, width), feeding structure (e.g. just a wire stub, a cone/triangle (for wider bandwidth), or if there is some other structure to provide some matching capabilities or whatever), the length of the horn as well as the form of the horn (e.g. exponential or just linear opening).

hi
what is your problem PLs attach your simulation in here or mail me
and about the gain i should say u i think a little more than common models and usually horn gain around 13-18Dbi
