Abstract

A novel structure for a compact waveguide-based CRLH phase shifter suitable for SIW technology has been developed. A simple design procedure is presented and verified by the simulation results based on the balanced CRLH TL equivalent circuit model. An eight-cell structure has been designed and optimized offering up to 270deg phase shift with a wideband performance over the frequency band (16-21 GHz). Future work includes further improvements in the phase shifter characteristics by modifying the waveguide width as well as the use of the developed structure in the design and fabrication of compact beam-forming matrices in SIW technology.
