A novel ultra‐wideband (UWB) out‐of‐phase power divider with band‐pass filtering response is presented.This power divider is constructed by introducing multilayer microstrip line‐slotline coupling structure, which can not only divide/combine the power of microwave signals, but also reject unwanted frequency signals. To verify the features of this proposed out‐of‐phase power divider, one prototype divider is designed, fabricated, and measured. Good impedance matching, amplitude balance, and out‐of‐band rejection are obtained both by simulations and measurements. © 2010 Wiley Periodicals, Inc.
