In this letter, a novel zero‐order‐resonant composite right/left‐handed transmission line (CRLH‐TL) is investigated and its equivalent circuit is proposed. Both the numerical simulations and the theoretical analysis show that the zero‐order resonant frequency occurs at 1.42 GHz, due to introduction of the spiral inductor, and the stop band between the left‐handed pass band and the right‐handed one disappears. We measure experimentally the five‐stage CRLH‐TL. The measurement results are in agreement with those of the simulations and theory. The CRLH‐TL with zero‐order resonant has potential for applications in miniaturization of microwave devices. © 2009 Wiley Periodicals, Inc.
