This article examines a wideband impedance transformer based on a split ring resonator and defected ground structures. The transformer was designed as a 4 section binomial one and it provides a transformation from 50 SI to 100 Omega. Reversed "Z" shaped defects are formed on the ground plane of the design in order to increase the bandwidth. The design has been simulated using a 3D electromagnetic simulator which utilizes finite integration technique. Three distinct resonances are exhibited at specific frequency spots as proofs of the concept of impedance matching. Theoretical and simulated results are in a good agreement with each other and the proposed design might be tailored in many microwave circuits and antenna applications.
