Estimation of dielectric constant for various standard materials using microstrip ring resonator

, 2017
Microstrip ring resonator (MRR) is known for dielectric constant determination and many studies used Teflon as a standard sample. However, there are many other materials available which able to perform better or equivalence as the Teflon in calibrating ...
