1. a planar horn antenna for phase alignment, 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 embedded metal via hole (3);

  • First port (5) of described microstrip feed line (1) is the input/output port of this antenna, and second port (6) of microstrip feed line (1) connects with substrate integration wave-guide horn antenna (2);

    Substrate integration wave-guide horn antenna (2) to be connected the first metal flat (8) and the second metal flat (10) by the first metal flat (8) being positioned at medium substrate (4) one side, the second metal flat (10) of being positioned at medium substrate (4) another side two rows with through medium substrate (4) via hole trumpet side walls (11) that metallizes forms;

    The first metal flat (8) in substrate integration wave-guide horn antenna (2) and the second metal flat (10) all have several gaps (3), the length in gap (3) is greater than a wavelength, the one end in gap (3) is in the inside of substrate integration wave-guide antenna (2), the other end in gap (3) is close but less than antenna opening diametric plane (13), gap (3) form multiple sub-loudspeaker (12) in the inside of substrate integration wave-guide loudspeaker (2);

    The shape in described gap (3) is broken line, exponential line and other curve etc., and the width of different gap (3) can be different, and the width of every bar gap (3) can be uneven;

    In described one or several gap (3), adjust distance between adjacent two gaps (3) or the distance between an adjustment gap (3) and substrate integration wave-guide horn antenna (2) sidewall metallization via hole (11) or change the length of one or more of gap (3), can make to arrive the upper electromagnetic wave PHASE DISTRIBUTION in bore face (13) of antenna evenly, or the upper electromagnetic wave phase place in bore face (13) arriving antenna is distributed as required;

    Regulate the width of certain gap (3), electromagnetic phase velocity in the sub-loudspeaker (12) on this gap (3) both sides can be changed, can make to arrive the upper electromagnetic wave PHASE DISTRIBUTION in bore face (13) of antenna evenly, or the upper electromagnetic wave phase place in bore face (13) arriving antenna is distributed as required.
