NOVEL MICROSTRIP BAND-STOP FILTERS BASED ON COMPLEMENTARY SPLIT RING RESONATORS.

In this article, the stop-band characteristics of cornplementary split ring resonators (CSRR) and their applications to microstrip band-stop filters are proposed. The equivalent circuit model of a unit CSRR is applied to explain its characteristics and the parameters of a circuit model are extracted from EM simulation and circuit theory. Two types of novel compact microstrip band-stop filters based on CSRRs are proposed and their frequency responses are simulated and measured. The measurements are in agreement with the simulations.
