Abstract
The utility model discloses a receiving antenna of a satellite TV, composed of a bracket assembly, a reflecting surface arranged on the bracket assembly and a feed source holding assembly arranged on the reflecting surface. The utility model is characterized in that the reflecting surface is composed of an engineering plastic basal body and a conducting reflecting layer printed on the basal body, and the conducting reflecting layer can be a netted or grille-shaped conducting reflecting layer. The utility model has the advantage that the paraboloid basal body of the antenna of the utility model is made by hot pressing type injection molding. The error of the reflecting surface is only determined by the mould, and has nothing to do with the material quality or the thickness of the sheet material. Therefore, the manufactured reflecting surface of the antenna has good dimension consistency and face type consistency. Because a reflecting surface conductive layer is printed on the antenna plastic basal body by conductive paste, the corrosion resistance of the reflecting surface is better than that of the metallic material. Therefore, no surface coating treatment is needed on the reflecting surface, so as to reduce the manufacturing cost of the antenna. The cost performance of the antenna product is better than that of the antenna made of metal plates and metal meshes.
Description
Technical field
The utility model relates to a kind of satellite television receiving antenna, exactly relates to the parabolic television receiving antenna of a kind of synchronous satellite earth station.
Background technology
Present commercially available synchronous satellite television receiving antenna all is to be operated in C-band (operating frequency 3.7GHZ～4.2GHZ) and KU wave band (operating frequency 10.7GHZ～12.75GHZ), in order to guarantee its working band width, make receiving paraboloid usually; The reflecting surface of parabolic antenna is to make of sheet metal or wire netting material, the reflecting surface that sheet metal is made, adopt the cold working shaped by fluid pressure, because the difference of sheet material material and the difference of thickness make the reflecting surface consistency of each antenna very poor because of springback capacity is different when causing moulding; Making reflecting surface with the wire netting material, is that wire netting is riveted on the framework, because framework needs cold stamping or shaped by fluid pressure, causes the consistency of reflecting surface to be difficult to guarantee equally.
Summary of the invention
The purpose of the present utility model is: for the user provides a kind of shape of product high conformity, corrosion-resistant, cost is low, cost performance is high satellite television receiving antenna.
Goal of the invention of the present utility model realizes by following technical proposals:
A kind of satellite television receiving antenna is become by thereon reflecting surface of bracket component, dress, the feed clamping component groups that is loaded on the reflecting surface, it is characterized in that: reflecting surface is made up of engineering plastics matrix and the conductive reflective that is printed on this matrix.
Additional technical feature is: a, be printed on the conductive reflective on the reflecting surface engineering plastics matrix surface, be netted conductive reflective.B, be printed on the conductive reflective on the reflecting surface engineering plastics matrix surface, be grid-like conductive reflective.
Advantage of the present utility model is: 1. because the parabolic matrix of the utility model antenna, by the heat pressing type injection mo(u)lding, the error of reflecting surface only depends on mould, and is irrelevant with material and sheet metal thickness, therefore size, the face type high conformity of the antenna reflective face that produces.2. owing on the antenna plastic substrate, be printed with the reflecting surface conductive layer with conductive paste, make the resistance to corrosion of reflecting surface be better than metal material, so not needing to carry out surperficial coated on reflecting surface handles, so just reduced the antenna manufacturing cost, make the ratio of performance to price of this antenna product, be better than the antenna of metallic plate, wire netting making.
