Description
Technical field
The present invention relates to a kind of horn antenna, especially a kind of thin substrate slot-line planar horn antenna.
Background technology
Horn antenna has a wide range of applications in the systems such as satellite communication, terrestrial microwave link and radio telescope.But the huge physical dimension of three-dimensional horn antenna constrains its application and development in planar circuit.In recent years, the proposition of substrate integrated waveguide technology and development well facilitate the development of planar horn antenna.Substrate integration wave-guide have size little, lightweight, be easy to integrated and the advantage such as processing and fabricating.Based on the substrate integration wave-guide planar horn antenna of the plane of substrate integration wave-guide except the feature with horn antenna, also well achieve the miniaturization of horn antenna, lightness, and be easy to be integrated in microwave and millimeter wave planar circuit.Traditional substrate integration wave-guide planar horn antenna have a restriction, the thickness of antenna horn aperture substrate is greater than 1/10th operation wavelengths, and antenna just can have good radiance, not so due to reflection, the energy emission in antenna is not gone out.So just require that the thickness of antenna substrate can not be too thin, L-band etc. comparatively low-frequency range to meet this requirement very difficult especially, very thick substrate not only volume and weight is very large, counteracts integrated advantage, but also adds cost.The polarised direction of these antenna radiation field is generally all perpendicular to medium substrate in addition, and some application needs the polarization parallel of radiation field in medium substrate.More existing antennas load the radiation that paster improves thin substrate plane horn antenna before planar horn antenna, but the patch size loaded is comparatively large, and working band is narrower.
Summary of the invention
technical problem:the object of the invention is to propose a kind of thin substrate slot-line planar horn antenna, the polarised direction of this radiation field of aerial is parallel with medium substrate, very thin medium substrate manufacture can be used, when the electric very thin thickness of substrate, still there is excellent radiance.
technical scheme:thin substrate slot-line planar horn antenna of the present invention, is characterized in that this antenna comprises the microstrip feed line be arranged on medium substrate, the integrated horn antenna of substrate and multiple line of rabbet joint loudspeaker; First port of described microstrip feed line is the input/output port of this antenna, and the second port of microstrip feed line connects with the integrated horn antenna of substrate; The integrated horn antenna of substrate to be connected the first metal flat and the second metal flat by the first metal flat being positioned at medium substrate one side, the second metal flat of being positioned at medium substrate another side two row's metallization via hole trumpet side walls with through medium substrate form, width between two row's metallization via hole trumpet side walls of the integrated horn antenna of substrate becomes large gradually, form one tubaeformly to dehisce, the end of dehiscing is the bore face of the integrated horn antenna of substrate; Multiple metallization arrays of vias is had to connect the first metal flat and the second metal flat in the integrated horn antenna of substrate, the length of each metallization arrays of vias is the same, the head end of metallization arrays of vias is inner at the integrated horn antenna of substrate, and the tail end of metallization arrays of vias is on the bore face of the integrated horn antenna of substrate; Row's metallization via hole trumpet side walls that two adjacent metallization arrays of vias or a metallization arrays of vias are adjacent, form dielectric-filled waveguide with the first metal flat and the second metal flat, outside bore face, each dielectric-filled waveguide is connected to a line of rabbet joint loudspeaker.
The conduction band of microstrip feed line connects with the first metal flat, and the ground plane of microstrip feed line connects with the second metal flat.
The width of dielectric-filled waveguide will make electromagnetic wave to propagate and not to be cut off wherein, and the length of dielectric-filled waveguide has more than half guide wavelength.
Each line of rabbet joint loudspeaker have the first radiation patch and the second radiation patch respectively on the two sides being positioned at medium substrate, first radiation patch of line of rabbet joint loudspeaker is connected with the first metal flat of the integrated horn antenna of substrate, second radiation patch of line of rabbet joint loudspeaker is connected with the second metal flat of the integrated horn antenna of substrate, and the hypotenuse of the first radiation patch and the hypotenuse of the second radiation patch open gradually and form flaring opening.
Metallize in via hole trumpet side walls and metallization arrays of vias, the spacing of two adjacent metallization via holes is less than or equals 1/10th of operation wavelength, makes the metallization via hole trumpet side walls formed can be equivalent to electric wall with metallization arrays of vias.
Electromagnetic wave inputs from one end of microstrip feed line, the other end through microstrip feed line enters substrate integration wave-guide horn antenna, after propagating a segment distance, run into metallization arrays of vias, just enter the transmission of each dielectric-filled waveguide respectively, the electromagnetic wave entering each dielectric waveguide enters line of rabbet joint loudspeaker radiation by antenna opening diametric plane, and the polarised direction of radiation field also becomes and connects subparallel horizontal direction with substrate.
Owing to there being multiple metallization arrays of vias that the bore face of antenna is divided into a lot of little bore faces, it is very little that the size of the line of rabbet joint loudspeaker that each osculum diametric plane connects can be done, and compact conformation, the size of such antenna also only increase seldom.
Antenna from feeding microstrip line to line of rabbet joint loudspeaker, be all closed substrate integrated wave guide structure, therefore feeder loss is less.
beneficial effect:the beneficial effect of the thin substrate slot-line planar horn antenna of the present invention is that the polarised direction of this radiation field of aerial is parallel with medium substrate; This antenna can use the medium substrate manufacture of thickness of wavelength lower than 2 percent, far below the substrate thickness of 1/10th wavelength required by usual planar horn antenna, when the electric very thin thickness of substrate, still there is excellent radiance, such as in 6GHz frequency, adopt the thickness of epoxide resin material substrate can be reduced to 0.5mm by 2.5mm, thus greatly reduce size, weight and cost; Compact conformation, the feeder loss of antenna are little.
