Abstract

In this work it is proposed new configurations for the ring resonator to determine with accuracy the dielectric permittivity of printed circuit boards operating at high frequencies. The procedure is determining the resonance frequency of the ring and its relation with the permittivity of the material. The results obtained are compared to the ones known for the classic configuration of the ring.
