Hi,
I'm trying to simulate a type of coaxial antenna as attached. The outer conductor is stripped off at one section, exposing the dielectric. And the inner conductor is extended.
This design is suppose to give a far-field radiation pattern similar to a half-wave dipole. However I tried modeling it in HFSS, I kept getting 4 lobes, instead of the desired 2 for the radiation pattern, and the S11 is horrible.
CAn anyone advise me where are my mistakes? Thankz!
Cheers
