Hey guys,
I have a planar microstrip structure on a piece of substrate and am simulating it within CST microwave studio.
There is a ground plane on the back and a strip on the top which the middle pin of a SMA connector would connect to.
From reading the CST help literature I assume that the waveguide port should be 6 to 10 times the width of the microstrip on top and should be 5 times the substrate height from top to bottom. I have also made the height a little bigger at the bottom so that it covers the ground plane.
The important dimesions are as follows:
Width of microstrip on top - 1mm
Thickness of substrate - 0.8mm
Thickness of microstrip - 0.03556mm
Therefore the box should be 6mm across and 4.03556mm high (starting at the bottom of the ground plane) right?
I have checked the port mode and it matches the fundemental mode example shown in the help literature.
I only want to check this is right as I have noticed the dimensions of the port can change the results as obviously I want accurate results.
Many Thanks!
