Waveguide apparatus

A radial waveguide apparatus for effecting bidirectional distribution of electromagnetic signals between at least one originating signal locus and at least one destination signal locus;

• the apparatus comprising:
• (a) a first substantially planar circular conductive element oriented substantially parallel with a reference plane;
• (b) a second substantially planar circular conductive element in spaced substantially parallel relation with said first conductive element;
• (c) a first signal coupling element situated substantially at the center of said first conductive element for effecting signal coupling with at least one first external device;
• and
• (d) a plurality of second signal coupling elements arrayed in said second conductive element substantially symmetrically about the center of said second conductive element;
• said plurality of second signal coupling elements effecting signal coupling with at least one second external device;
• said first signal coupling element being said at least one originating signal locus and said plurality of second signal coupling elements being said at least one destination signal locus when said distribution of said electromagnetic signals is effected in a first direction;
• said plurality of second signal coupling elements being said at least one originating signal locus and said first signal coupling element being said at least one destination signal locus when said distribution of said electromagnetic signals is effected in a second direction;
• each respective second signal coupling element comprising a respective aperture traversing said second conductive element in a respective radial plane perpendicular with said reference plane and containing a respective radius from said first signal coupling locus at a respective radial distance along said respective radius from said first signal coupling element;
• each said respective aperture being substantially rectangular and having a respective major axis and a respective minor axis;
• said respective major axis establishing a respective installation attitude for each said respective aperture with respect to said respective radial plane;
• said respective radial distance and said respective installation attitude for each said respective second signal coupling element being selected to provide said electromagnetic signals at substantially equal power levels on arriving at said at least one destination signal locus.
