Development of Wilkinson Power Divider for UWB Application

This paper presents the development of Wilkinson power divider using circular stub and a L-type parasitic short line. The design of power divider is started with conventional design of Wilkinson power divider. To observe the significant performance enhancement, the performance of proposed power divider is compared with the conventional design of power divider. To validate the proposed design, all of designs are investigated using Ansoft HFSS simulation tool. The simulated results of the proposed Wilkinson power divider is compared and analyzed. The overall simulated percentage bandwidth of the proposed power divider is 59.73%, ranging from 6.27 to 11.61 GHz frequency band.
