Description
Technical field
The present invention relates to a kind of horn antenna, especially a kind of three-dimension packaging skin antenna of embedded metal via hole phase amplitude calibration.
Background technology
Adopt little packaging technology, can be integrated in a radio system in the encapsulation, also need antenna is integrated in the surface of encapsulation for this reason.Be a kind of very natural mode at the integrated paster antenna of package surface, but the radiation master of paster antenna is to the normal direction that is the surface, and the radiation master that we need sometimes is to being direction surfacewise.If just can realize radiation along surface direction at the integrated horn antenna of package surface.But usually horn antenna is nonplanar, with incompatible, the larger physical dimension that has of planar circuit technique, thereby has limited its application on encapsulating structure.In recent years, substrate integration wave-guide horn antenna based on the substrate integrated waveguide technology development has the advantages that size is little, lightweight, be easy to Planar integration, but the gain of traditional substrate integration wave-guide horn antenna is relatively low, its reason is because horn mouth constantly opens, it is asynchronous phase place to occur when causing Electromagnetic Wave Propagation to the horn mouth diametric plane, the PHASE DISTRIBUTION of bore electric field strength is inhomogeneous, and radiation directivity and gain reduce; The amplitude of electromagnetic field is also very inhomogeneous on the bore face in addition, narrowing toward each end broad in the middle, and this also affects the radiance of antenna.The methods such as at present existing employing medium loading, medium prism, correct the asynchronous of horn mouth diametric plane phase place, but these methods all can not be improved the inconsistent of horn antenna and free space wave impedance on the bore face, can not improve the uniformity that electromagnetic field magnitude distributes on the bore face, and these phase alignment structures have increased the overall structure size of antenna, are not suitable for being integrated into package surface.
Summary of the invention

The circular hole that one end of metallization vertical vias feeder line passes on the metal flat of medium substrate bottom surface links to each other with the internal circuit of three-dimension packaging, there is individual circular pad on its other end top, metallization vertical vias feeder line top circular pad 10 is at the center of circular hole of the end face metal flat of medium substrate, and the end face metal flat of therefore metallize vertical vias feeder line top circular pad and medium substrate does not directly electrically contact.
The substrate integration wave-guide horn antenna is made of narrow Cross-section Waveguide Using and tubaeform waveguide serial connection; One end of narrow Cross-section Waveguide Using is short circuit face, and the other end of narrow Cross-section Waveguide Using links to each other with tubaeform waveguide, and an end of tubaeform waveguide links to each other with narrow Cross-section Waveguide Using, and the other end of tubaeform waveguide is the antenna opening diametric plane.
The intermediate metallization arrays of vias is positioned at the middle position of two sidewalls of substrate integration wave-guide horn antenna, and the substrate integration wave-guide horn antenna is divided into symmetrical two parts, in the both sides of the metallization arrays of vias of centre, symmetrical have left side dielectric-filled waveguide and a right dielectric-filled waveguide.
Metallization arrays of vias in the left side is divided into first medium to left side dielectric-filled waveguide and fills waveguide and second medium filling waveguide, and the right metallization arrays of vias is divided into the 3rd dielectric-filled waveguide and the 4th dielectric-filled waveguide to the dielectric-filled waveguide on the right.
Intermediate metallization arrays of vias, left side metallization arrays of vias and the right metallization arrays of vias shape all are to be linked to each other with three sections of tail end straightways by head end straightway, polygon to consist of, the head end of intermediate metallization arrays of vias, left side metallization arrays of vias and the right metallization arrays of vias is all towards the short circuit face direction of the narrow Cross-section Waveguide Using of horn antenna, the tail end of intermediate metallization arrays of vias, left side metallization arrays of vias and the right metallization arrays of vias stretches to the antenna opening diametric plane, but less than on the antenna opening diametric plane.
Head end straightway in intermediate metallization arrays of vias, left side metallization arrays of vias and the right metallization arrays of vias or the shape of tail end straightway can be straight line, broken line or exponential line etc., and its length can be zero or finite length; Polygon in intermediate metallization arrays of vias, left side metallization arrays of vias and the right 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.
Left side dielectric-filled waveguide, the right dielectric-filled waveguide, first medium fill waveguide, second medium fill the width of waveguide, the 3rd dielectric-filled waveguide and the 4th dielectric-filled waveguide all to guarantee its main mould can the on the left side dielectric-filled waveguide, the right dielectric-filled waveguide, first medium fill waveguide, second medium is filled transmission in waveguide, the 3rd dielectric-filled waveguide and the 4th dielectric-filled waveguide and is not cut off.
Select the position of polygon vertex in the intermediate metallization arrays of vias and select head end straightway in the left side metallization arrays of vias or polygon on the left side dielectric-filled waveguide in the position, can fill the again radiation to the bore face of antenna of port that the two-way electromagnetic wave constant amplitude homophase that transmits in the waveguide arrives dielectric-filled waveguide so that fill waveguide and second medium by first medium.
Select the position of polygon vertex in the intermediate metallization arrays of vias and select head end straightway in the right metallization arrays of vias or the polygon position in the dielectric-filled waveguide on the right, can be so that again radiation to the bore face of antenna of the port that arrives dielectric-filled waveguide by the two-way electromagnetic wave constant amplitude homophase that transmits in the 3rd dielectric-filled waveguide and the 4th dielectric-filled waveguide.
