Hello everyone,
I am simulating a monopole antenna with CPW feeding on a silicon substrate at 100 GHz in CST , I am using a waveguide port with the dimensions indicated on the help, however I have two questions :
1- Why does the line impedance change with the dimensions of the port? line impedance is the characteristic impedance of the line or the impedance on the port?
2- I noticed that using the "electric shielding" option improves my results a lot, I would like to know when I can use this option, and what it means.
thank you in advance.
