Abstract

In this work, a model based on a coupled transmission line formulation is developed for microstrip rectangular double split‐ring resonators (DSRRs). This model allows using the physical dimensions of the DSRRs as an input avoiding commonly used extraction of equivalent parameters. The model includes the compensation for the different circumference of two rings and allows the prediction of higher order resonance modes of the DSRR. The advantage of the developed model in comparison to the previously developed analytical representation is that it includes the coupling effect between neighboring DSRRs, which allows for an accurate modeling of densely packed multiresonator structures. The model is verified by comparison with measured DSRRs‐loaded microstrip line performance. The developed model can be effectively used to save computation resources associated with full wave electromagnetic simulations of the DSRR structures. © 2011 Wiley Periodicals, Inc.
