摘要：
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 degrees phase shifter designed using the proposed structure show more than 110% fractional bandwidth with a maximum phase deviation of +/- 3.3 degrees and maximum insertion loss of 0.8 dB.
