Background technology
That plate aerial has is in light weight, volume is little, occupy little space, advantages such as windage is little, efficient height, plate aerial has higher efficient with respect to the antenna of other forms such as parabolic antenna, it is higher to gain, volume is little, but the efficient of plate aerial is between 75%～80% at present, from the difficult efficient 80% that breaks through of technological layer, to realize higher efficient.
Existing flat plate antenna structure is various, but most technical conditions that only satisfy short-range communication:
For example, Chinese patent application CN 101752655A discloses a kind of plate aerial, comprises a substrate, a plurality of antenna body and a metal level.Described a plurality of antenna body is arranged on a surface of substrate, and metal level is arranged on another surface of substrate.Metal level has a plurality of grooves, interts respectively between described a plurality of antenna bodies.Described a plurality of antenna body is partly corresponding to metal level, and launches simultaneously and receiving electromagnetic signals in order to the communication system that cooperation has a plural multi-path transmission.But the operating frequency of this patent application is lower: 2.4GHz, though volume is less, the gain of whole plate aerial is not high, only satisfies the closely requirement of signal transmission in the practical application, and application is limited.
For example, Chinese patent application CN 101005156 discloses a kind of flat plate antenna of high gain wide band, in order to solve the problem that can't apply to high-gain broadband on the traditional antenna structure, plate aerial of the present utility model comprises microwave base plate, has first surface and second surface; The first symmetric form radiating element is disposed on this first surface, and this first symmetric form radiating element has first Department of Radiation and second Department of Radiation; The second symmetric form radiating element is disposed on this second surface, and this second symmetric form radiating element has the 3rd Department of Radiation and the 4th Department of Radiation; And at least one linkage unit, connect this microwave base plate and reflecting plate.Wherein the end of this first Department of Radiation, this second Department of Radiation, the 3rd Department of Radiation and the 4th Department of Radiation adopts step structure Design method.By flat plate antenna structure design of the present utility model, can realize the purpose of high-gain broadband.The described plate aerial volume of this patent is little, bandwidth is big, only satisfies in-plant communication requirement but himself gain, and is still not enough for the telecommunication gain; And this patent also is unfavorable for organizing battle array to realize higher gain.
For example, Chinese patent CN 101483271 discloses a kind of plate aerial, comprises: a dielectric layer, a radiation metal layer and a ground metal layer.This dielectric layer is made by insulating material, has a upper surface, a lower surface and a perforation.This radiation metal layer is coated on the upper surface of this dielectric layer, has one first lamellar body, corresponding with this perforation first perforation, and first convex extension part of being extended in this perforation by the first perforation periphery of this first lamellar body.This ground metal layer is coated on the lower surface of the medium layer, have one second lamellar body, corresponding with this perforation second perforation, and second convex extension part of extending in this perforation by the second perforation periphery of this second lamellar body, and this first convex extension part contacts in this perforation with this second convex extension part, this radiation metal layer is formed with this ground metal layer be electrically connected.Though it is higher that the plate aerial described in this patent gains, the processing simplicity of design, bandwidth is narrower, uses the microwave-medium plate efficiency low.
For example, Chinese patent CN101640309 discloses a kind of flat plate antenna structure, comprises first sheet metal, intermediate layer, becket and second sheet metal.Wherein the intermediate layer comprises first hole, and the intermediate layer is arranged on first sheet metal and with first sheet metal and links; Becket passes first hole and first sheet metal links; And second sheet metal comprises second hole, and second sheet metal and becket link, and second sheet metal links with first sheet metal, and intermediate layer and becket are by first sheet metal and the coating of second sheet metal.Whereby, second sheet metal can electrically conduct by the becket and first sheet metal, forms resonant cavity between first sheet metal and second sheet metal, and by the characteristic of the diameter adjustable antenna that changes first hole and becket.The described plate aerial design debug of this patent is comparatively simple, but its complex structure is difficult to processing, and it is lower to gain, and has used dielectric-slab efficient low.
For example, Chinese patent CN101719596A discloses the utility model a kind of single-feed source periodically arranged groove slot panel antenna is provided.The groove structure of arranging of some cycles that this antenna is loaded by ground plate and gap feed source both sides is formed, and the distance between slit and adjacent trenches is less than the groove cycle.Different with traditional period groove structure radiation mechanism, the electric field at groove place is opposite with the electric field phase at place, slit, can not see the groove place as source of secondary radiation again.At this moment, antenna surface has produced electromagnetic viscosimeter pattern-two an adjacent trenches integral body of another kind of novelty as a secondary radiation source, to the space radiation energy.It is compact more that this new antenna not only has structure, designs more flexible characteristic, and the conventional groove slot antenna identical with the groove number compared, and H face compression angle of the present utility model is littler, and antenna gain also improves.The more common antenna size of the described plate aerial of this patent is little, and gain is high, but the design debug complexity.
