Combining an electromagnetic band‐gap structure (EBG) and squared split‐ring resonators (SSRRs) in a planar microstrip line circuit, negative values of electric permittivity and magnetic permeability can be obtained. This phenomenon arises thanks to the negative permeability of the SSRR particles when they operate in the vicinity of their quasi‐static resonance frequency, and the negative permittivity due to the behavior of the EBG structure within the rejected frequency band. Therefore, a novel approach is presented in this article to synthesize a left‐handed media in microstrip technology. Full wave simulation results as well as measurement results from a fabricated prototype confirm the left‐handed behavior of the interaction. © 2007 Wiley Periodicals, Inc.
