Abstract :
A broadband 40-dB directional coupler using coupling slits opened in common ground conductors between parallel coaxial lines has been fabricated. Dielectric plates are loaded in the slits to compensate for the directivity degradation due to ground conductor discontinuities at the slit ends. The directivity is greater than 24 dB.<>
