An improved design of wideband Wilkinson power divider with stubs for wireless communication application

摘要

An improved design of wideband Wilkinson power divider with stubs concerning operating frequency of 2 to 7 GHz is presented in this paper. Power divider is designed by adding stubs at transmission line of Port 1, 2 and 3, which the position of stubs is studied for wideband application. CST Microwave Studio is used to design the proposed power divider and perform its parametric analysis. From the simulation results, the return loss is observed to be better by 1 dB and the bandwidth is 25% wider compared to the conventional Wilkinson power divider design.
