The design of a planar out‐of‐phase (180°) power divider with an ultra wideband performance is presented. The device employs two dielectric substrates with a common ground plane. A transition from a parallel stripline to two microstrip lines is formed to divide power equally and with 180° phase difference from a stripline input port to two microstrip line output ports. The simulated and measured results of the proposed divider show equal power division with high stability of phase, good return loss at the three ports, low insertion losses, and fine isolation between the two output ports across the band from 3 to more than 11 GHz. © 2007 Wiley Periodicals, Inc.
