Abstract

In this paper, we are going to present a methodology which is more suitable and easy to measure complex permittivity of dielectric substrates using ring resonator of a planar circuits. Mainly it is based on the transmission type ring resonator with capacity coupling. On adjusting base resonant frequency of a ring resonator we can measure the dielectric constant and dissipation factor at wide frequency  band and the remaining parameters can simplified or verified according to the information in this paper.
