HFSS Waveguide to Coax Transition

Hi,

I am working with an In-line Waveguide to Coax transition project for Ka band with a 2.92mm end launcher, I have created the 3-D model in HFSS and also specified the required dimensions for the steps and pin . After simulation the the S-parameters are not what I am looking for. The results show that the assembly is working in a very narrow band.

I want to know whether I have simulated the design correctly or am I making some trivial mistake?

Can anyone please help me solve my problem as I need it done ASAP?

Please let me know what all details do you require, I will provide all the details required.

Thank you.

Looking at your screenshots, I see no mistake.



Actually, I don't see any screenshots at all.

I am Sorry I will upload them Immediately !

I have attached the Screen shots.
