Abstract A compact ultrawideband (UWB) microstrip power divider (PD) with one sharply rejected notch‐band and wide stopband is analyzed and designed in this article.The proposed UWB PD is based on conventional Wilkinson PD, while interdigital hairpin resonators are introduced in two symmetrical output ports to widen passband. The stepped impedance resonator is studied and used to generate one desired notched band. Defected ground structure is introduced to improved stopband performance. Theoretical and simulated results are presented, which are in good agreement with the measured results. © 2012 Wiley Periodicals, Inc.
