Abstract
In this work, the effects of varying the series capacitance in metamaterial transmission lines consisting on a microstrip line loaded with complementary split rings resonators (CSRRs) and series capacitors are analyzed in detail. It is found that by varying the series capacitance, the transmission characteristics of the line can be tailored. Specifically, the typical transmission zero present below the left handed band, as well as the limits of this band, are modified. It is even possible to balance the line by properly tuning the structure. These results are interpreted to the light of the equivalent circuit model of the unit cell. Comparison between experiment and theory supports the interpretation of the results. This work opens the door to the design of reconfigurable microwave components based on complementary split rings resonator‐loaded lines. © 2007 Wiley Periodicals, Inc.
