1. the 3D-package surface antenna of the embedded phase amplitude calibration in gap, it is characterized in that this antenna comprises the metallization vertical vias feeder line (1) be arranged on medium substrate (4), substrate integration wave-guide horn antenna (2) and gap (3), medium substrate (4) is in the top of three-dimension packaging (5);

  • Described metallization vertical vias feeder line (1) is connected with the internal circuit (8) of three-dimension packaging (5);

    Substrate integration wave-guide horn antenna (2) by be positioned at medium substrate (4) one side bottom-side metal plane (6), be positioned at medium substrate (4) another side topside metal plane (9) and be connected bottom-side metal plane (6) through medium substrate (4), the metallization via hole trumpet side walls (11) of topside metal plane (9) forms;

    Bottom-side metal plane (6) and topside metal plane (9) have many gaps (3), the length in gap (3) more than a wavelength, and forms intermediate gap (16), gap, the left side (17) and gap, the right (18);

    Intermediate gap (16) is positioned at the position in the middle of two sidewalls (11) of substrate integration wave-guide horn antenna (2), and substrate integration wave-guide horn antenna (2) is divided into the sub-loudspeaker in the symmetrical left side (19) and the right sub-loudspeaker (20);

    Gap, the left side (17) is divided into the first sub-loudspeaker (21) and the second sub-loudspeaker (22) sub-for left side loudspeaker (19), and gap, the right (18) are divided into the 3rd sub-loudspeaker (23) and the 4th sub-loudspeaker (24) the sub-loudspeaker (20) on the right;

    A port of the first sub-loudspeaker (21), the second sub-loudspeaker (22), the 3rd sub-loudspeaker (23) and the 4th sub-loudspeaker (24) all towards short circuit face (15) direction of the narrow Cross-section Waveguide Using of antenna (13), its another port near but less than antenna opening diametric plane (12);

    Described intermediate gap (16), gap, the left side (17) and gap, the right (18) shape are all to be connected successively with end section three sections by head portion, polygon to form;

    Head portion in intermediate gap (16), gap, the left side (17) and gap, the right (18) or the shape of end section are straight line or broken line or exponential line;

    Polygon in intermediate gap (16), gap, the left side (17) and gap, the right (18) is the polygon that triangle or quadrangle or pentagon or other limit number are greater than five;

    The head end of intermediate gap (16), gap, the left side (17) and gap, the right (18) all towards short circuit face (15) direction of the narrow Cross-section Waveguide Using of horn antenna, the tail end of intermediate gap (16), gap, the left side (17) and gap, the right (18) near but less than antenna opening diametric plane (12).
