In this article, a circuit model is proposed for the complementary split‐ring resonators (CSRRs) loaded transmission line, and comparisons between the results derived from the equivalent circuit model and the experimental results are given and a good agreement between them over a wide frequency band supports the effectiveness of the proposed modeling methodology. Both the results show the negative permittivity at the vicinity of the resonance frequency of CSRR. By comparing the results of different periodic length (i.e., the capacitance per‐unit‐cell of the host microstrip line is changed), the validity of the equivalent circuit is further confirmed. © 2009 Wiley Periodicals, Inc.
