  • Abstract
    An original wideband two-layer substrate integrated waveguide directional coupler is presented. The structure provides attractive features including a flexible design with a wideband coupling and independent control of the transmission phase for arbitrary coupling levels. Characteristics of 18 dB isolation and 90 phase shift between direct and coupled ports are experimentally validated over 16 bandwidth.
