Dual-band unequal power-divider miniaturized by fully printed CRLH phase-shift lines

A fully-printed compact dual-band unequal power-divider is proposed. The branch lines with different impedances of the power-divider are replaced by small metamaterial phase-shift lines having +90° for UHF-band and −90° for WiMAX-band. Also, the CRLH property and the agreement between simulation and measurement are shown. The size is reduced by 3∼7times from the quarter-wavelength types.
