Abstract
A numerically demanding wideband matching transformer composed of three nonuniform transmission lines (NUTLs) has been designed and optimized at a low computational cost. The computational feasibility of the design has been acquired through the exploitation of low-fidelity NUTL models in most steps of the design procedure and an implicit space mapping optimization engine, providing high accuracy results with only a handful of EM simulations. The final design offers an enhanced functionality, that is, a 42% length diminution and has been acquired at the total cost of 12 EM evaluations of the entire structure. The method proposed has been experimentally validated, showcasing its usefulness for numerically demanding design problems of microwave circuits with complex topologies.
