ABSTRACT A wideband two‐way Gysel power divider/combiner is presented based on a modified Marchand balun. With a −15 dB input and output return loss criteria, proposed method has a bandwidth of about 53%, while dimensions are still similar to the conventional Gysel power divider/combiner. The structure of the designed planar microstrip in‐phase power divider is fairly simple, practical, and easily fabricated without requiring complex multiple metal or dielectric layers. In addition to CAD simulation and optimizations, with the aid of even‐ and odd‐mode analysis, a mathematical designing framework is also established. To verify the design approach, the proposed divider/combiner is fabricated and measured at the S‐band of frequency. There is a good agreement between simulation and experimental results. © 2017 Wiley Periodicals, Inc. Microwave Opt Technol Lett 59:949–955, 2017
