Problems solved by technology

[0002] At present, the known structures of radome are divided into: glued foam board, inflatable type, solid sheet with screwed flange, metal space frame + thin skin and honeycomb sandwich board connected by bolts, etc. The applicable microwave frequency band is below 10GHz , and in the case of small installation space, the metal parts will have a greater impact on the microwave signal, and the foam board or air will make the radome not strong enough
In addition, because the radome is spliced ​​and formed, it is difficult to deal with waterproofing

Embodiment Construction

[0010] Below the present invention will be further described in conjunction with the embodiment in the accompanying drawing:

[0011] Such as figure 1 As shown, it includes an inner glass cloth 1, a honeycomb panel 2, a glass cloth 3, a reinforcing ring 4 and a plastic nut 5.

[0012] The inner glass cloth 1 and the honeycomb panel 2 are bonded together by resin glue, the glass cloth 3 is bonded on the outer layer to form a wave-transparent composite interlayer, and the radome installation interface is bonded with glass filaments to form a reinforcing ring 4. Plastic nuts 5 are pre-embedded in the reinforcement ring 4 .

[0013] In the invention, suitable honeycomb material is added to the inner layer of FRP at the circumferential position to ensure the wave-transmitting performance and rigidity of the radome in a wide frequency band. It overcomes the interference of the metal parts of the existing radome to the microwave, the insufficient strength and the narrow applicable ...

Abstract

The invention relates to a wideband cellular interlayer fiber reinforced plastic antenna cover comprising an internal layer glass cloth, a cellular plate, a glass cloth, and a reinforcement ring. The internal layer glass cloth and the cellular plate are bonded together through resin adhesive. Then, the glass cloth is pasted on the outer side of the bonded internal layer glass cloth and the cellular in order to form a wave-transparent composite interlayer. The reinforcement ring is formed by pasting glass silk at an antenna cover installing interface. A plastic screw nut is pre-embedded in the reinforcement ring. The wideband cellular interlayer fiber reinforced plastic antenna cover has advantages of simple and reasonable structure, no metallic components, good rigidity and intensity and waterproof performance, and good wave-transparent performance and rigidity and intensity in a wide band.

Description

technical field [0001] The invention relates to a broadband honeycomb laminated fiberglass radome, which can meet the protection and wave penetration requirements of 2-18GHz antennas and is used for small integrated broadband antennas. Background technique [0002] At present, the known structures of radome are divided into: glued foam board, inflatable type, solid sheet with screwed flange, metal space frame + thin skin and honeycomb sandwich board connected by bolts, etc. The applicable microwave frequency band is below 10GHz , and in the case of small installation space, the metal parts will have a greater impact on the microwave signal, and the foam board or air will make the radome not strong enough. In addition, since the radome is spliced ​​and formed, it is more difficult to deal with waterproofing. Contents of the invention [0003] The purpose of the present invention is to overcome the above disadvantages and provide a broadband honeycomb laminated FRP radome. ...
