[0025] In order to facilitate the understanding of the present invention, the present invention is described in more detail below in conjunction with the accompanying drawings and specific embodiments. Preferred embodiments of the present invention are provided in the accompanying drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described in this specification. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0026] It should be noted that, unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0027] In the drawings, arrow X indicates the front direction, that is, the front-rear direction, arrow Y indicates the side direction, that is, the left-right direction, and arrow Z indicates the vertical direction, that is, the up-down direction.

[0028] Combination Figure 1 , Figure 2 and Figure 3The S-band satellite antenna includes a plurality of antenna units S1 and a plurality of corresponding transceiver synthesis units S2, and a base 1. The plurality of antenna units S1 are mounted on a support frame in a ring shape. Each transceiver synthesis unit S2 is correspondingly arranged below each antenna unit S1. The base 1 is arranged below the transceiver synthesis unit S2. The antenna unit S1 includes a first mounting plate S11 and a metal layer S12. The metal layer S12 is insulated and arranged on the upper surface of the first mounting plate S11 and is electrically insulated from the first mounting plate S11. An interface S21 is arranged on the top of the transceiver synthesis unit S2. The metal layer S12 is electrically connected to the interface S21. Specifically, there is a gap between adjacent antenna units S1. There are eight antenna units S1, eight transceiver synthesis units S2, and eight transceiver synthesis units S2. It is ring-shaped, and one antenna unit S1 corresponds to a transceiver synthesis unit S2 above and below. There is a gap between adjacent antenna units S1, that is, the multiple antenna units S1 enclosed in a ring are actually composed of eight independent small units, and the diameter of the ring formed by the eight antenna units S1 is 300mm. The significance of setting the gap is to divide the ring-shaped antenna unit S1 into multiple small units through the gap. The size of each small unit becomes smaller, which can reduce the influence of the entire ring-shaped antenna unit S1 on the radiation pattern and improve the low elevation angle gain. Therefore, multiple antenna units and corresponding transceiver synthesis units can be controlled separately, and then the synthetic radiation pattern of the antenna can be changed according to the spatial position of the satellite passing overhead, so that the direction of the antenna can change with the position of the satellite.

[0029] In actual applications, according to the spatial position of the satellite passing overhead, these transceiver synthesis units S2 and the corresponding antenna units S1 are powered on in a targeted manner, and not all of the transceiver synthesis units S2 and the corresponding antenna units S1 are kept working all the time. In this way, each transceiver synthesis unit S2 and the corresponding antenna unit S1 can be controlled separately, so that the required directional pattern can be synthesized, so that the spatial position of the satellite can be tracked more targetedly.
