A compact and low-loss band-pass waveguide resonator using higher order resonance of CSRR

Abstract

This paper presents a very compact band-pass waveguide resonator using second resonance of complementary split ring resonators (CSRRs). Analytical equations are used to calculate the resonance frequency of the CSRR. It has been predicted and verified experimentally that second resonance of the CSRRs has lower loss and larger bandwidth rather than first one.
