  Complex Permittivity of Dielectric Substrate Measurements Using Ring Resonator

  By Praveen Kumar Kancherla, S.V.S. Prasad, N. Nagaveni

  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 …
