✦ Synopsis

An efficient design procedure, including both analysis and synthesis, is proposed for Composite Right/Left Handed (CRLH) interdigital/stub structures. Improved models are developed for both the interdigital capacitor and the shorted stub inductor including its ground via hole. Subsequent optimal formulas are recommended to model these components with their parasitic effects. The models and formulas are verified by both fullwave and experimental results. A CAD program with a friendly GUI, available online, is provided and its operation is described in details. This program allows a very fast design of the CRLH structure, and its synthesis parameters are proven very accurate without any full-wave optimization. V

## Abstract A novel composite right/left‐handed transmission line is presented in this letter. The proposed CRLH structure can be considered as a CPW version composed with a pair of parallel spiral interdigital and a conjunctive stub. The spiral interdigital enlarges the series capacitance, and the
