I need help from you.I'm working on ADS (momentum) to simulate a Leaky Wave antenna based on Composite Right/Left Handed Structures (Metamaterials).I have the original article of Mr Caloz and Itoh "Dominant Mode Leaky-wave Antenna with backfire-to-endfire scanning capability".
My problem is how to terminate the antenna at Port 2 (in momentum) with a load impedance of 50Ω?
I have to do the same thing that you had , and I don't know how to make that via holes in ADS. I would appreciate it if you could send me the file with this antenna in ADS or tell me how to do.
