Design of dual-band wilkinson power divider using CRLH transmission line based on CSRR

Abstract

This paper presents a design of a dual-band Wilkinson power divider (WPD) with compact size and planer structure. A dual-band impedance inverter is design using composite right and left handed (CRLH) transmission line based on complementary split ring resonator (CSRR), which provides similar behaviors at the two frequencies. The above mention dual-band inverter is used to design dual-band WPD with equal and in phase outputs at the output ports, port '2' & port '3' for 1.57GHz and 2.9GHz frequency band. The proposed WPD is analyzed, fabricated and tested.
