Abstract
This paper proposes an improved equivalent circuit model for the composite right/left-handed transmission line (CRLH TL) and Dual-CRLH (DCRLH) TL unit cells. A pseudo-inverse technique is first implemented to extract the primary equivalent circuit. By using the conventional filter synthesis technique, the retrieval primary equivalent circuit is further transformed to a typical band-pass/band-stop filter circuit as the secondary equivalent circuit. With two-step retrieval procedure, the response of the secondary equivalent circuit can more accurately agree with that of CRLH/DCRLH TL unit cell in magnitude and phase of S parameters. Numerical results are given to demonstrate good performance of the proposed synthesis method.
