Description
Technical field
The invention belongs to the technical field of radome electrical property, and in particular to a kind of antenna house.
Background technology
Antenna house (Radome) is the covering being made up of natural or artificial dielectric's material, or by the electricity of truss support
The electromagnetism window for the special shape that medium housing is constituted.Antenna house cover wall cross-sectional configuration can be divided into uniform monolayers, Varying-thickness list
Layer, A- interlayers, B- interlayers, C- interlayers and sandwich construction etc..Higher carry-on antenna house should be required, typically using half-wave
Long wall construction.Influence of the antenna house to any antenna system, can be divided into single order influence and second order influence.Wherein, single order influence master
To depend on transmitance and insertion phase delay (Insertion phase delay, IPD) that antenna house changes with incidence angle.
They mainly influence directional diagram in antenna paraxial region to change, the skew of decline, beam position including antenna gain, ripple
The change of valve width and the increase of sidelobe level.For precise guidance type antenna house, the decline of antenna gain and wave beam
The skew of sensing will have a strong impact on the tactical qualities of weapon.Therefore, the transmission loss and IPD for how reducing antenna house are weapon dresses
Study hotspot in standby field.
At present, the transmission loss of (≤60 °) reduction antenna houses and IPD technology are mainly and use power transformation in wide angular region
The antenna house cover wall of degree.When on the antenna house cover wall of plane wave incidence to arbitrary shape, cover wall surface different zones correspondence is not
Same incident angle, as shown in Figure 1.As transmission loss and the IPD of the cover wall reduction antenna house using power transformation thickness, it would be desirable to
For in 20 °, 40 ° and 60 ° scanning ranges, optimizing different electric thickness.
The shortcoming of this method is：(1) surface of antenna house forms a kind of discontinuous structure, and transitional region is easily caused day
Line directional diagram distorts；(2) method of power transformation thickness not only increases radome electrical property energy optimization design difficulty, and increase
Prepare the technology difficulty of antenna house.
The content of the invention
In order to solve problems of the prior art, the invention provides a kind of antenna house, the antenna house is reduced pair
The single order influence of antenna system, improves the guidance precision of aircraft.
The technical proposal for solving the technical problem of the invention is as follows：
A kind of antenna house, including antenna cover body and internal structure；3 millimeters of sponge is provided with the antenna cover body
Layer, on the dielectric layer provided with 20-40 microns of layers of copper, the layers of copper surface is hexagon or pentagonal configuration；Antenna house
Global shape be two-dimensional curve structure；The wooden erection truss of internal structure gets up, in the reinforcement of well word machine structure.
The beneficial effects of the invention are as follows：After antenna house metal-loaded conducting screen, the directional diagram of radar antenna can be improved,
That is the loss of reduction antenna gain and reduction antenna beam skew, so as to improve the guidance precision of aircraft.After reinforcement, make
Overall structure is more firm, overall not increase resistance, and possesses thin, light, wide and strong technical characteristic.
Brief description of the drawings

Embodiment
The present invention is described in further details with reference to the accompanying drawings and examples.
A kind of antenna house, as shown in figure 3, the antenna house is to increase layers of copper 1 and spongy layer in the technology of ordinary antennas cover
2, spongy layer 2 is produced on ordinary antennas cover, and layers of copper 1 makes on the dielectric layer 2.As shown in figure 1, layers of copper 1 is by pentagon
Or hexagonal cells are constituted, wherein the width of pentagon or hexagon is 8 microns, when the unit cycle of layers of copper 1 is less than half wavelength,
Layers of copper 1 has relatively high and stable Q values.But, the transmission characteristic of layers of copper 1 is determined by infinite multiple not Lip river cover mold formulas, including
Holotype and higher order mode.Wherein, high-order mode belongs to evanescent mode, and it will influence the transmission of holotype.Therefore, master is not being influenceed
In the case that mould is transmitted, spongy layer 2 can decay higher order mode, so that main mould and high-order mode be separated.When in spongy layer 2
When opposite side loads the dielectric of arbitrary structures, in the range of wide scan angle, layers of copper 1 all has relatively high and stable Q values.Utilize
This characteristic, optimization current version antenna house or during development of new antenna house, we are by layers of copper 1 and spongy layer 2 and ordinary antennas
After cover is combined successively, using the relatively high and stable Q values of layers of copper 1, in the range of wide scan angle, the radome transmission in the present invention
Loss is decreased obviously compared with ordinary antennas cover.Moreover, the effective dielectric constant for supporting layers of copper 1, inventive antenna are utilized
Cover is lower than the insertion phase delay of generic media antenna house.
In the present embodiment, the preparation method of antenna house is as follows：Generate Japanese Feitian company in the preparation of layers of copper 1 25
The thick layers of copper 1 of micron utilizes semiconductor process technique, and corrosion prepares the shape shown in layers of copper 1 in Fig. 1, pentagon or hexagon
Width is 8 microns.When antenna house profile is extensible quadratic surface, using existing antenna house preparation technology, press
According to ordinary antennas cover → spongy layer → layers of copper order, the laminated new antenna cover prepared containing metallic conduction screen.Work as antenna house
When profile is not extensible quadratic surface, the burst on the anode membrane of autoclave is now needed to prepare layers of copper, then in layer successively
Close spongy layer and ordinary antennas cover.
The wooden erection truss of internal structure of antenna house gets up, in the reinforcement 3 of well word machine structure, it is therefore an objective to make antenna
The structure of cover is more consolidated.One maintenance door 4 is set on antenna cover body, when antenna house body interior needs to overhaul
Wait, antenna house body interior can be entered by maintenance door 4, maintenance door 4 is by adhesive tape in sealings in three weeks of door, and another side leads to
Cross folding and realize closure.
One bearing 5 is set in the bottom of antenna cover body, and bearing 5 is isosceles trapezoidal structure, and antenna house body is played
Supporting role.
