In this article, the effects of varying the geometry of complementary split ring resonators (CSRRs) in microstrip lines loaded with such resonant elements is analyzed. Specifically, from a parameter extraction technique previously proposed by some of the authors, the electrical parameters of CSRR-loaded lines (namely, the line inductance, the inductance and capacitance of the CSRR, and the coupling capacitance between the line and the CSRRs), are inferred. This analysis is of interest because, in spite of the existence of analytical models that predict the electrical parameters of these CSRR-loaded lines, the validity of these models is limited, and the parameter extraction method is necessary to accurately determine the electrical parameters from geometry. From the analysis carried out in this work, interesting conclusions for the design of CSRR-loaded lines are obtained. © 2008 Wiley Periodicals, Inc.
