Actually, I will utilize waveport for my antenna, Antipodal Vivaldi Antenna. It has not general feed shape like my attatched image. It has two different size metal plate across the dielectric substrate (I set the substrate transparent). So I have difficulty on setting the waveport.
Anyway, your...
Hello guys, I'm trying to calculate port impedance of the antipodal vivaldi antenna(AVA).
But as you know, AVA has metal-substrate-metal structure.
Each metal plates are for radiating, but at the balun stage, the one has a purpose for ground the voltage.
So, I have difficulty on setting the...
