On the use of Split-Ring Resonators and Complementary Split-Ring Resonators for Novel Printed Microwave Elements: Simulations, Experiments and Discussions
Abstract—Making use of either split-ring resonators (SRRs) or complementary split-ring resonators (CSRRs). As an example in this paper, simple 50-Ω microstrip lines are loaded with SRR and CSRR, and very compact band-reject filters have been obtained. Some important stop-band characteristics of these
filters have been studied and compared in a detailed manner. Simulations have been accompanied by measurements and good agreement has been obtained between numerical and experimental results.The advantage of using this kind of resonators for filter design is that they are significantly smaller insize than conventional resonator structures (generally less than one-tenth of a wavelength) enabling the design of very compact filters.
