Planar slot coupled microwave hybrid

Patent ·
OSTI ID:5533925
This patent describes an apparatus for propagating microwave energy. It comprises a dielectric substrate having first and second opposed faces a first conducting member disposed on the first face of the dielectric substrate including a first portion having a longitudinal center line and terminating at a first end in a first port and having a second end, and second and third portions connected to the second end of the first portion extending away from the center line to terminate at second and third ports respectively; and a ground plane disposed on the second face of the dielectric substrate, the ground plane having a gap therein defining an elongated slot parallel to and opposite the first portion and aligned with the center line for creating a slot coupled section, and arranged for energy propagation between the slot coupled section and a fourth port.
