Co-axial excitaion in HFSS?

Hello Friends,
I have one doubt in coaxial excitation in waveguide.
I have one waveguide structure where I will receive dual polarisation signal in frequency range 1-3GHz.
Can anybody tell me how to assign waveport here.
I have made one equivalent drawing in HFSS & attached here.
if anyone can show me how to excite ports here? it will be very helpful.
Please show the excitation in the file i have attached & re-upload.

Thanks,
Abhishekabs

Can you uploaded as an image or send it by email,I dont have enough points to download it

You dont need points to download this file
its size is only 5.27KB.

If size is > 512KB then only you need points.

ok I have it,how do I upload it here?

Hello, I am facing one problem in simulation.
I get this error message every time.

"[error] Port refinement, process abc3d : Port "WavePort2" is incorrectly set up. A port must have a non-existent material on one side. Both "Box1" and "cover2" exist. "


What is the meaning of this?
Cover 2 is teflon of coaxial abale, & box1 is air box surrounding structure(horn)
Please find the images attached.
( Basically I am trying to simulate Horn).
