Hello
If you have a patch antenna in CST, you must apply the boundaries to the antenna sides, bottom and top.
The bottom (ground plane) is an electric plane (Et=0) the top is open (add space).
BUT the sides are named open. My question is, will CST exstend the materials (substrate, ground plane) that close up to these boundaries to infinity? I mean will it extend the substrate and ground plane to infinity?
Hope it makes sense.
Thank you
