Modeling and Simulation of Wilkinson Power Splitter in Suspended StriplineAbstract
This paper offers one possible solution to the problem of different phase velocities in even and odd mode during the design of Wilkinson power splitters. This topic is especially important in the design of modern beamforming networks for military and space applications where low insertion loss is required and obtained through a use of suspended stripline and other extremely (ultra) inhomogeneous platforms. A new approach is proposed where even and odd mode quarterwave transforming sections of a multi-section Wilkinson splitter do not end at the same locations. The approach has been implemented through an algorithm that calculates all critical parameters of the splitter. In order to confirm the practicality of the proposed solution, various examples of Wilkinson splitters have then been developed through the algorithm and then simulated using SONNET® and other electromagnetic software tools. The developed configurations have, also, been compared to the conventional ones to evaluate the improved performance.
