Problems solved by technology
For example, compared to the dish design of F / D=0.4, the dish design of F / D=0.6 needs to match the beam with a narrower beam width. If the beam width does not meet the dish design (such as too wide or too narrow), it will affect the receiving performance of the satellite antenna and reduce the receiving quality of the satellite signal
[0005] However, currently there is no related device for adjusting the beam width of the horn antenna on the market, so it is impossible to improve the compatibility with different dish designs

Embodiment Construction
[0022] Please refer to figure 1 , figure 1 It is a schematic diagram of a beam adjusting device 10 according to an embodiment of the present invention. The beam adjusting device 10 is used for a horn antenna 100 , and the horn antenna 100 includes an opening 102 and a ring 104 surrounding the opening 102 . exist figure 1 Among them, the beam adjusting device 10 is composed of a metal guide (conductor), which is used to adjust the beam formed by the horn antenna 100 according to the dish surface characteristics of a satellite antenna (not shown in the figure) corresponding to the horn antenna 100. wave width. Wherein, the dish surface characteristic may be a focal length diameter ratio. It should be noted that the metal guide of the beam adjustment device 10 can be in symmetrical geometric shapes such as orthogonal crosses, concentric rings, point-like eccentric circles, or radiation divergence, and can pass through a fixing piece (not shown in the figure) The horn antenna...

The invention discloses a beam wave adjusting device for a horn antenna. The horn antenna comprises an opening and a ring body surrounding the opening. The beam wave adjusting device comprises a metal conducting piece and a fixing piece, wherein the metal conducting piece is used for adjusting the width of a beam wave formed by the horn antenna according to the disc surface characteristic of a satellite antenna corresponding to the horn antenna; the fixing piece is used for fixing the metal conducting piece on the horn antenna; the satellite antenna is used for receiving a signal sent by the horn antenna. In the invention, the required width of the beam wave can be obtained on the basis of different disc surface designs under the condition that the size of a horn antenna mould is not changed, so that the received information quality is improved; and the beam wave adjusting device provided by the invention can also maintain the same width of the beam wave under the condition that the size of the opening of the horn antenna is shortened so that the disc surface designs are matched and the cost is effectively reduced.
Description
technical field [0001] The invention relates to a beam adjustment device, especially a beam adjustment device for adjusting the width of a beam formed by a horn antenna. Background technique [0002] Satellite communication has the advantages of wide coverage and no interference from the ground environment. It is widely used in military, detection and commercial communication services, such as satellite navigation, satellite voice broadcast or satellite TV broadcast. The known satellite communication receiving device is composed of a dish reflector (Dish Reflector) and a wave collector (Low Noise Block Down-converter with Feedhom, LNBF). Receive the radio wave signal reflected by the dish-shaped reflector, down-convert the radio wave signal to an intermediate frequency, and then send it to a satellite signal processor at the back end for signal processing, so that the public can watch satellite TV programs. [0003] The wave collector consists of a horn antenna (Feedhom), a...
