Description
Technical field
The invention belongs to communication and receive field, be specifically related to a kind of high wave hollow structure antenna house.
Background technology
Antenna house is one of the critical piece that can normally work under various severe environmental conditions in order to protective cover internal antenna, is
It is used for protecting antenna and a kind of medium shell of transmission electromagnetic signal, it requires that radome material must except on intensity and toughness
Must reach beyond requirement, broadband must pass through electromagnetic wave simultaneously.At present, it is applied to radome material and is mainly monolayer entity
Wall construction, wherein monolayer solid wall structure is owing to its processing technique is simple, intensity is higher, at present by universal a large amount of employings, but
Owing to its dielectric parameter ε (3.6-3.63) and loss angle tangent tg δ (0.008-0.009) are relatively big, Electromagnetic wave penetrating percentage is relatively
Low so that when using as antenna house, Antenna Design difficulty strengthens, and this impact cannot thoroughly solve, and can only pass through sky
These defects are contained in line global design, the most just reduce or sacrifice some index performances of antenna.
Summary of the invention
It is an object of the invention to provide a kind of high wave hollow structure antenna house.
For solving above-mentioned technical problem, the technical solution adopted in the present invention is as follows:
A kind of high wave hollow structure antenna house, including antenna house body, the sidewall of antenna house body includes hollow fabric layer.
Above-mentioned antenna house, intensity height, light weight, easy to manufacture, cheap, and be lost low, wave transmission rate is high, can be used as
Various types of antenna protections, fully meet the requirement of antenna performance various for antenna house, it is achieved that higher wave transmission rate,
Decrease the loss of electromagnetic wave.
The inner surface of hollow fabric layer is compounded with inner layer composite material layer.So can improve the intensity of antenna house and extend use
Life-span.
The outer surface of hollow fabric is compounded with outer layer of composite material layer.So can further improve the intensity of antenna house.
The thickness of inner layer composite material layer and outer layer of composite material layer is 0.2-3.0；Inner layer composite material layer and outer layer are combined
The dielectric parameter of material layer is all below 3.The most not only can ensure the intensity of antenna house, and have high wave transmission rate, high
Reach more than 97%.
Inner layer composite material layer and outer layer of composite material layer are infiltrated by resin glue and fabric and are composited, and resin glue is not
Saturated resin, epoxy resin (EP), cyanate ester resin (CE), polyimide resin (PI) or bimaleimide resin
(BMI) mixture of one or more any proportionings in.So while ensureing antenna house intensity, can guarantee that sky
The wave transmission rate that irdome is high.
Fiber used by hollow fabric layer, inner layer composite material layer and outer layer of composite material layer be glass fibre, quartz fibre,
The mixture of one or more any proportionings in basalt fibre or aramid fiber.Hollow fabric layer, inner layer composite material layer and
Fine more preferably same fiber used by outer layer of composite material layer.The most both can guarantee that the wave transmission rate that antenna house is high, and can strengthen again
The intensity of antenna house.
The thickness of hollow fabric layer is 2.0-20.0；Dielectric parameter is below 3, and loss tangent is less than 0.007.This
Sample can improve and improve the transmitance of antenna house, ensures the intensity of antenna house simultaneously.
Hollow fabric includes upper epidermis, sandwich layer and layer the most connected in order, and sandwich layer is by being shaped as " 8 " font, " mouth "
The fabric unit composition of font or " X " font.The most not only ensure that antenna house use intensity all and wave transmission rate,
And make antenna house have lighter quality, considerably reduce the manufacturing cost of antenna house simultaneously.
The density of fabric unit is 10000-300000/m2.So can ensure the most simultaneously antenna house intensity and
Wave transmission rate.
Antenna house body longitudinal section be shaped as mushroom-shaped, rectangle, circular or oval.
The moulding process of above-mentioned antenna house has hands paste, injection, pultrusion, mold pressing etc., it is also possible to be between above-mentioned moulding process
Combination.
During use, the thickness of each layer can go out suitable thickness by dielectric parameter and loss tangent Theoretical Calculation or simulation calculation
Degree.
The NM technology of the present invention is prior art.
The structure of height wave hollow structure antenna house of the present invention and ordinary antennas cover is completely different, and entirety of the present invention uses three-dimensional
The features such as hollow structure, has wave transmission rate good, and novel structure is unique, can fully meet antenna performance various for antenna house
Requirement；Compared with monolayer solid wall structure, honeycomb-type structural and the half-wavelength structure of prior art, the present invention is comprehensive
With all advantages of above-mentioned all structures, having cost-effective, high-strength light and manufacturing process are simple, and wave transmission rate is high
Feature, can protect inner antenna device in all cases, and wave transmission rate can reach more than 97%；With honeycomb-type structural phase
Ratio, wave transparent performance is suitable, but manufacturing process is simple, and cost is relatively low, is suitable for producing in enormous quantities；Compared with half-wavelength structure,
Applicable band width, can reduce the weight of antenna and save material, and cost is lower.
