Cross-polarized microwave antenna

Claim 1

A CROSS-POLARIZED LINEAR ARRAY MICROWAVE ANTENNA FOR RADIATING MICROWAVE ENERGY IN ONE POLARIZED PLANE FOR RECEIVING MICROWAVE ENERGY IN TWO DIFFERENT POLARIZED PLANE INCLUDING, A RECTANGULAR WAVEGUIDE HAVING AN INPUT END AND AN OUTPUT END FOR TRANSMISSION OF MICROWAVE ENERGY, A HYBRID JUNCTION COUPLED TO SAID INPUT END AND SAID OUTPUT END, MEANS FOR PROVIDING MICROWAVE ENERGY TO SAID WAVEGUIDE TO ESTABLISH STANDING WAVE PATTERNS THEREIN COMPRISING FIRST AND SECOND WAVEGUIDE WALL CURRENTS, SAID CURRENTS HAVING VALUES WHICH ARE SUBSTANTIALLY 90* OFFSET WITH RESPECT TO EACH OTHER AT A COMMON POINT IN SAID WAVEGUIDE, A FIRST PLURALITY OF ELEMENTS IN THE WALL OF SAID WAVEGUIDE FOR EFFECTIVELY RADIATING AND RECEIVING MICROWAVE ENERGY IN A FIRST POLARIZED PLANE WHEN SAID FIRST CURRENT IS SUBSTANTIALLY MAXIMUM AT SAID COMMOM POINT, A SECOND PLURALITY OF ELEMENTS IN THE WALL OF SAID WAVEGUIDE FOR EFFECTIVELY RADIATING AND RECEIVING MICROWAVE ENERGY IN A SECOND POLARIZED PLANE WHEN SAID SECOND CURRENT IS SUBSTANTIALLY MAXIMUM AT SAID COMMON POINT, SAID MEANS TO ESTABLISH SAID STANDING WAVE PATTERNS COMPRISING, A FIRST ARM ASSOCIATED WITH SAID HYBIRD JUNCTIONS AND OPERATIVE TO PROVIDE A FIRST STANDING WAVE PATTERN WHEREBY SAID FIRST CURRENT IS SUBSTANTIALLY MAXIMUM AT SAID COMMON POINT AND SAID SECOND CURRENT IS SUBSTANTIALLY MINIMUM AT SAID COMMON POINT AND SAID FIRST CURRENT IS COUPLED TO SAID FIRT PLURALITY OF ELEMENTS, A SECOND ARM ASSOCIATED WITH SAID HYBRID JUNCTION AND OPERATIVE TO PROVIDE FOR PROVIDING A SECOND STANDING WAVE PATTERN WHEREBY SAID SECOND CURRENT IS SUBSTANTIALLY MAXIMUM AT SAID COMMON POINT AND SAID FIRST CURRENT IS SUBSTANTIALLY MINIMUM AT SAID COMMON POINT AND SAID SECOND CURRENT IS COUPLED TO SAID SECOND PLURALITY OF ELEMENTS, AND MEANS FOR SELECTIVELY APPLYING MICROWAVE ENERGY TO SAID FIRST ARM FOR PROVIDING SAID FIRST STANDING WAVE PATTERN AND FOR ALTERNATELY APPLYING MICROWAVE ENERGY TO SAID SECOND ARM FOR PROVIDING SAID SECOND STANDING WAVE PATTERN.
