An Unequal Broadband Power Divider Using Composite Right/Left-Handed Transmission Lines

摘要：

A unequal power divider using anti-coupled and Microstrip Metamaterial Lines over a large bandwidth is proposed. The structure comprises anti-coupled power divider, followed by a+900 negative-refractive index (NRI) metamaterial (MM) phase-shifting line along the top branch, and traditional microstrip line along the bottom branch. The structure is used to deliver flexible variation of power division ratio and phase using Composite Right/Left-Handed Transmission Lines (CRLH-TL), besides, anti-coupled power divider to suppress the second harmonic. The proposed power divider exhibits a measured differential output phase 900 ± 50bandwidth from 1.62 to 2.75GHz, while the output quantities S21 and S31 remain above-4dB from 0.7 to 2.5GHz.
