Abstract

A planar phase shifter with ultra‐wideband performance is presented.The proposed device utilizes a single‐section broadside‐coupled coplanar waveguide structure that can be implemented using a double‐sided printed circuit board. The conformal mapping technique is used to find the proper dimensions of the device. The simulated and measured results of a 45° phase shifter designed using the proposed structure show more than 110% fractional bandwidth with a maximum phase deviation of ±3.3° and maximum insertion loss of 0.8 dB. © 2011 Wiley Periodicals, Inc.

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
