Abstract

Abstract

This paper proposes a compact balanced Wilkinson power divider based on artificial transmission lines using double-sided parallel-strip lines. The design consists of artificial transmission lines to replace conventional transmission lines to save circuit size. In the meantime, the structure of double-sided parallel-strip lines is introduced to achieve balanced function. The proposed power divider is about 25% the place of a conventional divider. The measurements show that such a balanced Wilkinson power divider at operational frequency ranging from 0.83 GHz to 1.05 GHz has 1.28 phase balance and 0.17 dB amplitude balance. At all ports return losses are more than 16.79 dB and good isolation between the two output ports is greater than 16.21 dB. The measurements agree well with simulation results, demonstrating that this power divider has good performance.
