The conduction band of microstrip feed line and the first metal flat join, and the ground plane of microstrip feed line and the second metal flat join.
The shape of described metallization arrays of vias is connected and forms with three sections of tail end broken lines by head end broken line, polygon, polygon in metallization arrays of vias can be triangle, quadrangle, pentagon or other polygon, and the shape on a polygonal limit or many limits can be straight line, camber line or other curve; Head end broken line in metallization arrays of vias or the shape of tail end broken line can be straight line, broken line or exponential line etc., and its length can be to approach zero or finite length.
The width of dielectric-filled waveguide will make electromagnetic wave can propagate therein and not be cut off.
In described metallization arrays of vias, adjust the distance between adjacent two row metallization arrays of vias or adjust the distance between a row metallization arrays of vias and substrate integration wave-guide horn antenna side-wall metallic via hole, can change the width of dielectric-filled waveguide, and then be adjusted at the phase velocity of Electromagnetic Wave Propagation in this dielectric-filled waveguide (15), make to arrive the power on PHASE DISTRIBUTION of magnetic wave of antenna opening diametric plane more even.
In described metallization arrays of vias, the length that changes row or multiple row metallization arrays of vias can change the length that respective media is filled waveguide, makes to arrive the power on PHASE DISTRIBUTION of magnetic wave of antenna opening diametric plane more even.
Select head end broken line or position and the size of polygon in the integrated horn antenna of substrate in metallization arrays of vias, the electromagnetic wave power transmitting in each dielectric-filled waveguide is equated.
Each Quasi-Yagi antenna is comprised of an active dipole, one or several parasitic element; Active dipole has respectively the first radiation arm and the second radiation arm on the two sides of medium substrate, the first radiation arm of Quasi-Yagi antenna active dipole is connected with the first metal flat of the integrated horn antenna of substrate, the second radiation arm of Quasi-Yagi antenna active dipole is connected with the second metal flat of the integrated horn antenna of substrate, and the first radiation arm and second radiation arm of each Quasi-Yagi antenna active dipole stretch in the opposite direction; Parasitic element is positioned at any one side or the two sides of medium substrate can.

In the power on PHASE DISTRIBUTION of magnetic wave of antenna opening diametric plane, mainly by length and the width of each dielectric-filled waveguide, determined, adjust the position of the metallization head end broken line of arrays of vias and the position of tail end broken line and length and polygon vertex, just can regulate electromagnetic wave in the relative phase velocity of each dielectric waveguide transmission, and then make by the bore face of the electromagnetic wave homophase arrival antenna of each dielectric-filled waveguide, on antenna opening diametric plane, the field intensity amplitude distribution of each dielectric-filled waveguide port is the same with phase place like this.
Electromagnetic wave from each dielectric waveguide enters Quasi-Yagi antenna radiation by antenna opening diametric plane, because the radiation arm of left half antenna Quasi-Yagi antenna and the radiation arm of right half antenna Quasi-Yagi antenna are symmetrical, therefore the polarised direction of left half antenna Quasi-Yagi antenna radiation field is contrary with the polarised direction of right half antenna Quasi-Yagi antenna radiation field, and so just the direction at parallel medium substrate has formed difference beam.Quasi-Yagi antenna, in main radiation direction, is equivalent to a linear array, has higher gain, and therefore with respect to common plane horn antenna, this antenna has very high gain, has namely increased by zero dark and slope of difference beam.
