Abstract: This paper presents a novel CRLH transmission line using the split-ring resonator defected ground structure (SRR DGS). The equivalent-circuit values of the cell model are extracted by the curve-fitting technology, and then the transmission zero location, dispersive relation, refraction index and transmission characteristic of the cascaded structures are derived. Both theoretical and experimental results indicate that this structure possesses a composite right/left-handed property. The novel CRLH transmission line has an out-of-band transmission zero and compact structure with no grounded via, which can be widely applied in microwave integrated circuits.

Key words: split-ring resonator, defected ground structure, composite right/left-handed transmission line, transmission zero
