Hello PlanarMetamaterials,
I need to know how to model the circular slot as per attach photo in HFSS, I did try using substract (which is the circular patch substract perturbation), however my response doesn't change. I also want to know how is the exact way to calculate the radius of slot in mathematical way. I really need an example tutorial on slot/notch creating on a patch using hfss to understand better.
I have another doubt, may I know how can I calculate the width and length of the 50 ohm feeding line if I am using suspended stripline?
