Use of harmonics of microstrip ring resonator structure on determination of dielectric properties

Dielectric properties of printed wiring boards play a key role in many antenna application designs. The focus of this paper is to study effects of the harmonics of the ring resonator to determination uncertainty. For this purpose an experimental research of harmonics of the microstrip ring resonator is carried out. Results of the research offer essential information about determination of dielectric properties by using microstrip ring resonator structures.
