I'm a HFSS newbie and are having troubles with something I think should be quite simple. I'm trying to connect a 50 Ohm port to a piece of coax, which forms part of a coaxial colinear antenna. This sort of thing:
**broken link removed**
The coax has an inner, dielectric, braid and sheath. The dielectric properties of the sheath are possibly important in this application, so I gave that in my model. See attached file.
I want to connect the coax connector across the bottom of the antenna (at z=9 mm). But I'm puzzled how to do this. I've done it before, but get a warning that the port only has one connection.
The big cylinder which surrounds the antenna is my radiation boundary. An Ansof engineer said it was better to use a cylinder than a box for my application, as it is essentially a cylindrical antenna.
