coaxial feed xfdtd

I Don't know how to creat the coaxial cable , There is a coaxial cabel at the manual but I didn't understand it ? and why there is two ports in the cable ? and what are the polarity of them ? and which edge will be connected to the antenna ?

I Hope that if any could upload a geometry file for the coaxial cable connected to a simple antenna .

Thank you .

Haven't used it lately, but with version 6.3 or earlier, you have to draw the coaxial line and excit it with a "lumped port". There is no option for "wave port" in xfdtd.

Is The goemetry in the attachment right ??
it must be a 50ohm coaxial port feed the circular disc monopole through the ground plane.
it didn't give me results as the paper and I don't know how to draw the coax port

plz help

I'm also working on it. The same problem is encountered.
The test results will be posted sooner or later.
Please wait...
