CSRR Embedded CPW Band-Stop Filter

Abstract

This paper proposes topologies for narrowband and broadband notch filters using complementary split ring resonators (CSRR) in coplanar waveguide (CPW) technology. Simple analysis justifies these topologies. Strong coupling between the resonator and the signal line in these topologies can reduce the radiation loss in the stop-bands. Characteristics of these filters realized from electromagnetic simulations match closely with those from measurements on prototypes.
