摘要

A novel mm-wave rat-race coupler with broadband operating bandwidth based on parallel microstrip lines is presented in this paper. The useful practical bandwidth for this hybrid covers a frequency range 20–42 GHz for both sum and difference situations. The proposed design could be easily fabricated by printed circuit board (PCB) technology.
