Description

A kind of high wave hollow structure radome
Technical field
The invention belongs to communication and receive field, be specifically related to a kind of high wave hollow structure radome.
Background technology
Radome is one of the critical piece that can normally work under various severe environmental conditions in order to protective cover internal antenna; for protecting a kind of medium shell of antenna and transmission electromagnetic signal; so require radome material except must reach requirement on intensity and toughness, must broadband see through electromagnetic wave simultaneously.At present, being applied to radome material is mainly individual layer solid wall structure, wherein individual layer solid wall structure is because its processing technology is simple, intensity is higher, at present by general a large amount of employing, but due to its dielectric parameter ε (3.6-3.63) and loss angle tangent tg δ (0.008-0.009) larger, Electromagnetic wave penetrating percentage is lower, while making to use as radome, Antenna Design difficulty strengthens, and this impact cannot thoroughly solve, can only contain these defects by antenna global design, so just reduce or sacrifice some index performances of antenna.
Summary of the invention
The object of this invention is to provide a kind of high wave hollow structure radome.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is as follows:
A high wave hollow structure radome, comprises radome body, and the sidewall of radome body comprises hollow fabric layer.
Above-mentioned radome, intensity is high, quality is light, easy to manufacture, cheap, and loss is low, wave transparent rate is high; can be used as various types of antenna protections; meet antenna completely for the requirement of the various performances of radome, realized higher wave transparent rate, reduced electromagnetic loss.
The inner surface of hollow fabric layer is compounded with inner layer composite material layer.Can improve like this intensity of radome and increase the service life.
The outer surface of hollow fabric is compounded with outer layer of composite material layer.Can further improve like this intensity of radome.
The thick 0.2-3.0 ㎜ that is of inner layer composite material layer and outer layer of composite material layer; The dielectric parameter of inner layer composite material layer and outer layer of composite material layer is all below 3.So not only can guarantee the intensity of radome, and have high wave transparent rate, up to more than 97%.
Inner layer composite material layer and outer layer of composite material layer are composited by resin glue and fabric infiltration, and resin glue is the mixture of one or more any proportionings in unsaturated-resin, epoxy resin (EP), cyanate ester resin (CE), polyimide resin (PI) or bimaleimide resin (BMI).When guaranteeing radome intensity, can guarantee the wave transparent rate that radome is high like this.
Hollow fabric layer, inner layer composite material layer and outer layer of composite material layer fiber used are the mixture of one or more any proportionings in glass fibre, quartz fibre, basalt fibre or aramid fiber.Hollow fabric layer, inner layer composite material layer and outer layer of composite material layer fibre used be same fiber more preferably.The wave transparent rate that radome is high can be guaranteed like this, the intensity of radome can be strengthened again.
The thickness of hollow fabric layer is 2.0-20.0 ㎜; Dielectric parameter is below 3, and loss tangent is less than 0.007.Can improve like this and improve the transmitance of radome, guarantee the intensity of radome simultaneously.
Hollow fabric comprises upper epidermis, sandwich layer and the lower top layer that order is joined up and down, and sandwich layer is comprised of the fabric unit that is shaped as " 8 " font, " mouth " font or " X " font.So not only guarantee radome working strength and wave transparent rate all, and made radome have lighter quality, significantly reduced the manufacturing cost of radome simultaneously.
The density of fabric unit is 10000-300000/m 2.Can further guarantee intensity and the wave transparent rate of radome so simultaneously.
Radome body longitudinal section be shaped as mushroom-shaped, rectangle, circle or oval.
The moulding process of above-mentioned radome has hand paste, injection, pultrusion, mold pressing etc., can be also the combination between above-mentioned moulding process.
During use, the thickness of each layer can by dielectric parameter and loss tangent theory calculates or simulation calculation goes out suitable thickness.
The NM technology of the present invention is prior art.
The structure of the present invention's high wave hollow structure radome and common radome is completely different, and the three-dimensional hollow structure of the whole employing of the present invention, has wave transparent rate good, and the features such as novel structure uniqueness, can meet antenna completely for the requirement of the various performances of radome; Compare with individual layer solid wall structure, honeycomb type structure and the half-wavelength structure of prior art, the present invention combines all advantages with above-mentioned all structures, there is saving cost, high-strength light and manufacturing process are simple, wave transparent rate high, can protect in all cases antenna internal components, wave transparent rate can reach more than 97%; Compare with honeycomb type structure, wave penetrate capability is suitable, but manufacturing process is simple, and cost is lower, is applicable to producing in enormous quantities; Compare with half-wavelength structure, applicable band is wide, can reduce the weight of antenna and save material, and cost is lower.
