Investigação de métodos de medição de permissividade elétrica de placas de circuito impresso.

Abstract

In this work it is proposed new configurations of the ring resonator to measure, with greater accuracy, the permittivity of dielectric materials used in the design of printed circuit boards that operate at high frequencies. The procedure is determining, through measurements, the resonance frequency of the ring and its relation with the permittivity of the substrate. The samples used are obtained in the trade. The results obtained are compared to the ones for the classic configuration of the ring resonator.
