Abstract

A novel dual passband filter using hybrid microstrip split ring resonators and coplanar wavelength (CPW) quarter wavelength resonators is presented. An equivalent RLC circuit model is presented, and its corresponding parameters are also extracted from the theoretical analysis. The proposed dual passband filter has two passbands with the center frequencies of 2.44 GHz and 3.5 GHz. Good agreement among equivalent circuit (EC), electromagnetic (EM) simulated and measured results is demonstrated.
