Public award description

SLOT COUPLED PATCH ARRAY ANTENNA TECHNOLOGY THE PROPOSED PROJECT IS AN ANTENNA ARRAY WHOSE BEAM IS CONTROLLED DIGITALLY. THE PHASE 1 EFFORT WILL ASSESS THE METHOD NEEDED TO ACHIEVE THE GAIN, BANDWIDTH, AND PATTERN (3 DB BEAM-WIDTH AND SCAN FIELD OF VIEW). THIS IS BASED ON THE LEVEL OF CURVATURE AND INTERFERENCE/GEOMETRY OF THE VEHICLE ON WHICH IT IS TO BE MOUNTED. PHASE 1 FOCUSES ON THE FABRICATION AND TESTING OF ONE ELEMENT AND A SUB-ARRAY OF FOUR ELEMENTS ON A SIMILAR SURFACE SUCH AS A METALLIC OR DIELECTRIC WITH SOME DEGREE OF CURVATURE. PHASE 1 ALSO USES THE LMS ALGORITHM TO ADAPTIVELY PERFORM BEAM SHIFTING AND CORRECTION FOR PHASE SHIFT. PHASE 2 WILL INCREASE THE NUMBER OF ELEMENTS IN THE ARRAY AND ALLOW FOR SCANNING IN BOTH PLANES. ALSO, PHASE 2 WILL CONSIDER MORE COMPLICATED GEOMETRY AS REQUIRED TO DELIVER A FUNCTIONING ANTENNA ARRAY MOUNTED TO THE SPACE VEHICLE.
