Description
Technical field
The utility model relates to electromagnetic wave shielding field, in particular a kind of New Radar Absorbing radome.
Background technology
Electromagnetic wave is the major way of electromagnetic energy travels, during high-frequency circuit work, and the outside radiated electromagnetic wave of meeting, interference is produced to contiguous miscellaneous equipment, on the other hand, the various electromagnetic waves in space also can sense in sensitive circuit, impact the service behaviour of device.The largest benefit using electro-magnetic shielding cover to solve electromagnetic interference problem is the normal work that can not affect circuit, does not also need to make any amendment to circuit simultaneously.
Common metal radome can improve the radiation of components and parts, but electromagnetic energy does not weaken, and can penetrate screening arrangement by other means.Can know from the mechanism of electromagenetic wave radiation, electromagnetic energy in communication process mainly Electric and magnetic fields alternation spread to surrounding, traditional electro-magnetic shielding cover has following deficiency: 1) only carry out reflection loss to electromagnetic wave, can not reduce electromagnetic energy.2) the higher and narrow range of screening frequencies, generally at more than 1GHz.3) because electromagnetic energy does not reduce, likely generation secondary or triple-frequency harmonics are to external radiation, change electromagnetic wavelength, have an impact to follow-up electromagnetic shielding.4), the heavier mass of shielding case.In addition, when universal shield covers on reflection electromagnetic wave, inner generation parasite current, causes secondary electromagnetic interference.For this reason, the technical scheme that the utility model proposes can well solve problems.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides the aluminum radome that a kind of inwall is pasted with absorbing material layer.This New Radar Absorbing radome can utilize self reflection and re-absorption effect, electromagnetic energy is reduced greatly, causes electromagnetic radiation level far below relevant criterion.This New Radar Absorbing radome, be to provide to inhale a ripple space, make electromagnetic wave to the external radiation initial stage, just reflected and absorbed, only radome front need be assemblied in the surface of radiation prototype part, length and width size is 5 times of conductively-closed device length and width size, namely effectively can reduce radiation level, and can shield most of electromagnetic interference of 2Mz to 1Ghz.
The utility model is achieved through the following technical solutions: a kind of suction ripple radome, comprise aluminum hull, aluminum hull comprises roof and sidewall, aluminum hull has one point earth at least, the roof of aluminum hull and side walls enclose form the cavity of a bottom surface opening, the sidewall of aluminum hull extend horizontally away a mount pad in bottom respectively to surrounding, inhale ripple radome and also comprise one deck absorbing material layer and one deck silicone grease double faced adhesive tape, absorbing material layer paste aluminum hull inwall, the bottom of mount pad is provided with the flange stretched out in the inner part downwards, the inner side of flange is mutually concordant with the inside sidewalls of aluminum hull, silicone grease double faced adhesive tape is on the bottom surface of mount pad, flange height is not more than the thickness of silicone grease double faced adhesive tape.
As the further improvement of this programme, described suction ripple radome is also provided with installing hole, and installing hole is arranged on mount pad, and installing hole runs through mount pad from top to bottom.
As the further improvement of this programme, the cross sectional shape of the cavity of the bottom surface opening that the roof of aluminum hull and side walls enclose are formed is rectangle.
The utility model has the following advantages compared to existing technology:
1, change little to original circuit design and other designs, an emphasis shields radiation source, for follow-up work provides operating space.
2, on the basis do not increased, significantly reduce electromagnetic to external radiation and the protection to Sensitive Apparatus, improve the interference free performance of product.
3, the electromagnetic radiation after final assembly is limited within the specific limits, after assembling, can improve overall Electro Magnetic Compatibility, thus increase the competitiveness of product with subscriber's main station
4, the radiation of radiation source generation, forms multiple reflections in absorbing material layer inside, can reach and fall low-energy effect, thus shielding action is strengthened.
5, higher and wider range of frequency of shielding, effectively can shield the electromagnetic wave of 2MHz to 1GH.
6, the setting of inwall flange, while guarantee radome safety adhesion is on element, can reduce element with
7, secondary or triple-frequency harmonics can be avoided, reduce electromagnetic radiation intensity.
8, shield the lighter weight of aluminum hull, conveniently install on electric elements and fix.
9, processing is installed convenient, makes simple, with low cost, as long as the dimensional measurement of conductively-closed device is good, just from processing, then absorbing material laminating in inner side, only can need be arranged on device surface by inhaling ripple radome, just can play good shield effectiveness.

Embodiment
Below embodiment of the present utility model is elaborated; the present embodiment is implemented under premised on technical solutions of the utility model; give detailed execution mode and concrete operating process, but protection range of the present utility model is not limited to following embodiment.
As depicted in figs. 1 and 2, a kind of suction ripple radome, comprise aluminum hull 1, absorbing material layer 3 and silicone grease double faced adhesive tape 6, aluminum hull 1 has one point earth at least, aluminum hull comprises roof 4 and sidewall 5, roof 4 and sidewall 5 surround the cavity of a formation bottom surface opening, the cross sectional shape of cavity is rectangle, the sidewall 5 of aluminum hull 1 extend horizontally away a mount pad 2 in bottom respectively to surrounding, absorbing material layer 3 paste aluminum hull 1 inwall, silicone grease double faced adhesive tape 6 is attached on the bottom surface of mount pad 2, the bottom of mount pad 2 is provided with the flange 8 stretched out in the inner part downwards, the inner side of flange 8 is mutually concordant with inside the sidewall 5 of aluminum hull 1, flange 8 is highly not more than the thickness of silicone grease double faced adhesive tape 6.Inhale ripple radome and be also provided with installing hole 7, installing hole 7 is arranged on mount pad 2, and installing hole 7 runs through mount pad 7 from top to bottom.
Described New Radar Absorbing radome is installed to the device surface needing shielding, be connected with shielded body by silicone grease double faced adhesive tape 6, simultaneously, because the effect of flange 8, further strengthen element and extraneous isolation, for some specific positions, when needing radome oppositely install or vertically install upward, this programme also provides installing hole 7, is more firmly fixed on element by radome by using screw.Said structure makes device be limited in certain space, because the impedance (0.05 Ω) of electromagnetic wave shielding aluminum hull when spatial is much smaller than the wave impedance (377 Ω) of air, so can reflect on the surface of shielding aluminum hull 1, enter into the inside of absorbing material layer 3, because the material of absorbing material layer 3 itself has high magnetic conductivity, and internal material has certain energy loss to electromagnetic wave, so can decrease through the electromagnetic energy of absorbing material layer 3, reflection repeatedly, the electromagnetic wave energy being radiated space can be dropped to minimum, thus reach the effect of shielding.Because the use of this New Radar Absorbing radome does not change original circuit design, the impact for circuit is little.Thus the space radiation effectively solved because circuit devcie causes.
These are only preferred embodiment of the present utility model, not in order to limit the utility model, all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection range of the present utility model.
