1. the encapsulation interlayer antenna of a gap phase amplitude calibration, it is characterized in that this antenna comprises the microstrip feed line (1) be arranged on medium substrate (4), substrate integration wave-guide horn antenna (2) and gap (3), medium substrate (4) internal layer in three-dimension packaging (5);

  • Described microstrip feed line (1) is connected with three-dimension packaging (5) internal circuit (8) by co-planar waveguide (7);

    Substrate integration wave-guide horn antenna (2) by be positioned at medium substrate (4) one side bottom-side metal plane (9), be positioned at medium substrate (4) another side topside metal plane (10) and be connected bottom-side metal plane (9) through medium substrate (4), the metallization via hole trumpet side walls (11) of topside metal plane (10) forms;

    Bottom-side metal plane (9) and topside metal plane (10) there are 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);

    Gap, the right (18) is 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) is all towards microstrip feed line (1) direction, and its another port is all in 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, the head end of intermediate gap (16), gap, the left side (17) and gap, the right (18) is all towards microstrip feed line (1) direction, and the tail end of intermediate gap (16), gap, the left side (17) and gap, the right (18) reaches on antenna opening diametric plane (12);

    Head portion in described 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 limit number are greater than five;

    Select the position of polygon vertex in intermediate gap (16) and select the position in the middle head portion in gap, the left side (17) or the sub-loudspeaker of polygon on the left side (19), can make to arrive on the bore face (12) of antenna by the two-way electromagnetic wave constant amplitude homophase of transmission in the first sub-loudspeaker (21) and the second sub-loudspeaker (22);

    Select the position of polygon vertex in intermediate gap (16) and select the position on the right in sub-loudspeaker (20) of head portion or polygon in gap, the right (18), can make on the bore face (12) by the two-way electromagnetic wave constant amplitude homophase arrival antenna of transmission in the 3rd sub-loudspeaker (23) and the 4th sub-loudspeaker (24).
