Abstract

A comparative investigation of split-ring resonator (SRR)and complementary split-ring resonator (CSRR)-based band-reject filters is performed. These compact band-reject filters are obtained by loading simple 50-Ω microstrip lines with SRRs and CSRRs that have exactly the same shape and dimensions. Unlike the previous studies, stopband characteristics of these filters, such as resonance frequency, band-width, sharpness, and amount of attenuation in the rejection region based on the number of SRR or CSRR stages, are investigated in a detailed and comparative manner. Based on simulations that are accompanied by experimental results, it has been observed that some of the aforementioned stopband characteristics of SRR-based band-reject filters are significantly different than those of CSRR-based band-reject filters. This makes SRR- or CSRR-based filters preferable depending on applications.
