BROADBAND MULTI-SECTION STEPPED TAPERED MICROSTRIP TRANSFORMERS DESIGN USING SEEKER OPTIMIZATION ALGORITHM

This work applies an evolutionary searching algorithm of the Seeker Optimization Algorithm for designing multi-band multi-section stepped tapered microstrip lines that maximally match real load impedance to a transmission line in a pre-described range of frequencies. Seeker Optimization algorithm has been verified to be a very effective algorithm in finding the solutions for such multi-objective functions. Herein the design process aims to select the values of the matching impedances between real load and transmission line among a continuous range of values under tapering constraints. The obtained results have been verified by PUFF simulator and the design parameters have been calculated using the PUFF microwave simulator.
