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. © 2007 Wiley Periodicals, Inc.
