How to Feed a Microstrip Line Using an Infinite Substrate

Various methods are presented on how to feed a microstrip line using an infinite planar multilayer substrate in CADFEKO.

A microstrip line consists of a signal conductor (transmission line) fabricated on top of a dielectric substrate with a conductive ground plane at the bottom.
