Broadband structures for waveguide hybrid tee's

Claim 1

AN H-PLANE FOLDER HYBRID TEE REECTANGULAR-WAVEGUIDE JUNCTION COMPRISING AN E-PLANE ARM, AN H-PLANE ARM, AND TWO COMMON ARMS FOLDED IN AN H-PLANE BOUNDED BY THEIR TOP WIDE WALLS IN A FIRST COMMON PLANE AND THEIR BOTTOM WIDE WALLS IN A SECOND COMMON PLANE, SO AS TO SHARE A COMMON JUNCTION REGION FOR EACH SAID ARM BOUNDED BY SAID TOP AND BOTTOM WIDE WALLS, AND MEANS FOR MATCHING EACH SAID ARM AT SAID REGION SO THAT POWER FED INTO THE E-PLANE ARM DIVIDES INTO TWO EQUAL COMPONENTS 180* OUT OF PHASE IN THE COMMON ARMS, POWER FED INTO THE H-PLANE ARM DIVIDES INTO TWO EQUAL COMPONENTS IN PHASE IN THE COMMON ARMS AND POWER FED INTO EITHER COMMON ARM DIVIDES INTO TWO EQUAL COMPONENTS IN THE E-PLANE ARM AND THE H-PLANE ARM, WHEREIN THE IMPROVEMENT COMPRISES A PLURALITY OF ELECTRICALLY INDUCTIVE MEANS EXTENDING BETWEEN THE TOP AND BOTTOM WIDE WALLS ACROSS SAID COMMON REGION SYMMETRICALLY ON EITHER SIDE OF THE EPLANE ARM IN SAID REGION FOR REACTIVELY MATCHING SAID EPLANE ARM TO SAID COMMON REGION, THE GEOMETRY OF AN END WALL OF SAID REGION IS ADJUSTED FOR REACTIVELY MATCHING SAID H-PLANE ARM TO SAID COMMON REGION, SAID COMMON ARMS ARE FOLDED PARALLEL AND SHARE A COMMON NARROW WALL, AND THE REMAINING NARROW WALLS OF SAID COMMON ARMS EXTEND TO SAID END WALL TO PROVIDE AN ENCLOSURE FOR SAID COMMON REGION WHICH IS SUBSTANTIALLY OF UNIFORM ELECTRICAL WIDTH FROM SAID COMMON TO SAID END WALL.
