Size reduction and performance improvement of a microstrip Wilkinson power divider using a hybrid design technique

Abstract In the design of a microstrip power divider, there are some important factors, including harmonic suppression, insertion loss, and size reduction, which affect the quality of the final product. Thus improving each of these factors contributes to a more efficient design. In this respect, a h...
