Hi
I am working with a CPW-fed folded slot antenna and I am using waveport in HFSS.
The CPW was designed to has an impedance of 50ohms .The size of the waveport was: width =3(s+2W) and height =7H, because Strip line (S)>substrate thickness (H). Port only simulations showed that Port(Zo) is 50 ohms. However, the Port(Zo)changes when I modify the dimensions of the antenna, although the CPW is not modified. I don′t know If I need to change the waveport size everytime I change the antenna dimensions even when the CPW remains the same?
Thanks for your help!

download the tutorial about CPW port.
good luck
