How to create a coaxial port in HFSS

Hello, i need to create a Coaxial port for my Microstrip Patch Antenna. The antenna gives expected results using lumped port, i tried using coaxial port but was unable to achieve the same results.
Can any one help me in creating Coaxial port HFSS 13.
Antenna is Edge coupled. I have attached the HFSS file.
Thank You..

Can anyone help me plz.....

hi there, see attached tutorial. It walks you through creating a coax port using waveport (not lumped port).

Good Luck.

Thank you very much it helped me ... :)
