Abstract :
A GaAs MMIC technology of the novel dual composite right/left-handed (D-CRLH) transmission line (TL) is presented. The D-CRLH is the dual of the conventional CRLH in the sense that it consists of an LC parallel-tank impedance and of an LC series-tank admittance. This topological duality results into dual properties. In contrast to the conventional CRLH TL which has LH operation at low-frequency and RH one at high-frequency, the D-LH TL exhibits its LH band at high frequencies and its RH band at low frequencies, a property that may be exploited in various kinds of component and antenna applications. The proposed D-CRLH prototype exhibits a DC to 2.9 GHz right-handed (RH) band and a 5.1 GHz to 6.9 GHz left-handed (LH) band. The results in this paper are obtained from full-wave analysis, and they will be followed next by experimental results
