Abstract
The purpose of this thesis to provide alternative design procedure for a power divider that has broadband characteristics. The Wilkinson power divider consisting of cascaded quarter wave sections is known to increase the bandwidth while maintaining high isolation and good match conditions at individual ports. Resistors placed between the quarter wave sections served to increase isolation. The values of required components were determined using odd and even mode analysis. In this work, the approximate theory developed previously is used as a preliminary design model, and it is extended further by considering optimization techniques and coupling between adjacent arms. This novel approach is implemented on the existing software package "Microwave Design System", Hewlett-Packard Company. Results for uncoupled and coupled lines were obtained and comparisons were made. The overall performance of this design resulted in higher isolation and better matching properties. Furthermore, it was observed that monotonic change in separation between coupled lines and isolation resistor values became non-monotonic. The designed hybrid power dividers are currently being fabricated to be measured experimentally to validate the design.
