I have a material whose dielectric properties need to be measured. I have done literature review on the physics & impedance based methods to determine the dielectric component.
It requires S11 to be measured. I can design circuits and PCB's along with embedded system development but dont have a great knowledge about RF, Can anyone suggest on how to proceed further?
I read about VNA's to measure S11, can that be done using a custom miniature circuit for 4.5 GHz (using any relevant IC like AD5933)
