Abstract

A novel microwave power divider based on composite right/left-handed transmission line (CRLH TL) is presented. The power divider is composed of a segment of CRLH TL and several microstrip lines coupled with it. This design is based on the zeroth order resonance of CRLH TL. A prototype power divider at 2.4 GHz is presented. Unequal power division can be easily achieved. It is very compact along the longitudinal direction. The total insertion loss of the proposed CRLH power divider is less than 1.2 dB. Good phase balance and isolation among output ports are obtained.
