Broadband Fixed Phase Shifters

open access: yesIEEE Microwave and Wireless Components Letters, 2011
A method to design planar and compact phase shifters with broadband characteristics is presented. It utilizes broadside-coupled microstrip-coplanar waveguide, and thus the proposed devices can be fabricated using the simple and cheap double-side printed circuit boards. The method is used to design 60° and 90° phase shifters.

Energy-Efficient Hybrid Beamforming with Variable and Constant Phase Shifters

open access: yesApplied Sciences, 2019
In this paper, the authors propose a novel partially connected hybrid beamforming (PC-HBF) architecture, which employs variable phase shifters (VPSs) and constant phase shifters (CPSs) for analog beamforming to harness the potential of these two types of

Ultra-Wideband Phase Shifters

open access: yesIEEE Transactions on Microwave Theory and Techniques, 2007
A method with clear guidelines is presented to design compact planar phase shifters; with ultra-wideband (UWB) characteristics. The proposed method exploits broadside coupling between top and bottom elliptical microstrip patches via an elliptical slot located in the mid layer, which forms the ground plane.
