Coaxial Cable connection to Antenna

Please login with a confirmed email address before reporting spam

Hello Guys, I´m new with COMSOL and I try to simulate a quarter wave antenne which is excited by a SMA connector. I designed the coaxial cable like person did it in this tutorial https://www.comsol.com/video/intro-to-electromagnetics-modeling-with-comsol-multiphysics. But now I don´t know how to connect my antenna with the coax cable. Which boundaries do I have to use and is there a gap between the antenna and the coax cable? Thanks for your help

Haha of course, sorry. I want to do a frequency domain simulation to see the electric field. It is a system of one quarter wave antenna, sorrounded by three couplers on a ground plate. You can see a picture in the attachment(the left one). The Antenne should be excited by the coaxial cable but I don´t know how to connect them or which boundaries to use. picture: https://imgur.com/a/3CMU8
