Dual-band Wilkinson power divider based on composite right/left-handed transmission lines

Abstract

In this paper, an interdigital transmission line (ITL) based on the concept of composite right/left handed (CRLH) transmission line is introduced for the first time. By cascading interdigital capacitors, the ITL is created. The equivalent circuit of the interdigital capacitor and interdigital transmission line are expressed. Moreover, by utilizing the interdigital transmission line, a dual-band Wilkinson power divider is proposed.
