**broken link removed**, in addition to many others, have used a half-wave resonator as a generic model used towards completion of whatever goal.
For anyone who can't view the paper, it pictures a gap-coupled half-wave resonator with feed lines much narrower than the resonating patch.

Hi all,
I'm trying to do some calculations for expected pinch-off voltage for a simple MESFET that might be fabricated as future research and the numbers seem to be coming up high (or maybe not - I guess I'm not sure). I've checked some of the MESFETs on digikey but the pinch-off is either not...
For your antenna impedance, you can use linecalc I believe. You'll have to have the antenna designed in order to do this but once you do, you just plug in details such as dielectric constant, antenna width, etc.
As for using stubs for a matching network, you're essentially asking us to...
I believe most software has you input the relative permittivity and calculates the effective for you. I know that ADS and HFSS do, but I've never used Txline...
I assume at those frequencies you'll be using distributed elements rather than lumped which ADS is good for.
For the matching network, I would first start with the smith chart, figure out the length of the stub needed and its distance from the load (antenna), then plug those values into ADS...
