An unequal dual-band power divider with composite left/right-handed transmission lines

Abstract

Aiming at overcoming the drawback that a conventional power divider can only operate at a fixed frequency and its odd harmonics, a miniaturized unequal power divider operating at 1 GHz and 2.2 GHz is presented. The miniaturization is achieved by realizing the power divider′s impedance transformer using composite right/left-handed(CRLH) transmission lines(TLs). According to the theoretical and simulated results, the input terminal of the divider has good return loss and output terminals have good isolation result. Simulation result agrees well with theoretical one, which verifies the feasibility of this method.
