Description of the new type: [Technical field to which the new type belongs] This creation relates to the structure of the feeder of the dish antenna. The feeder is formed by bending both sides of the metal plate in the same direction into a gate shape. The appearance size is only about 10x10x30mm, which can greatly reduce the area and space occupied by the feeder, so that the reflection efficiency of the metal reflector is relatively improved, and the radiation gain value of the small-sized dish antenna is increased. [Prior art] As shown in the first and second figures, the conventional dish antenna structure is a directional antenna with directivity. The main structure includes a metal reflector 100 and a feeder 101. The metal reflector 100 Increase the radiation receiving and transmitting benefits of the feeder 101. Generally speaking, the appearance size and volume of the feeder 101 of the conventional dish antenna are relatively large. Referring to the first and second figures, the appearance size of the feeder 101 of the dish antenna is about 70x70x200mm. In the case of the metal reflecting plate 100, the volume of the feeder 101 occupies and blocks the reflecting surface of the metal reflecting plate 100, reduces the radiation gain efficiency of the dish antenna, and shortens the effective distance for radiation transmission and reception, and its use range is limited. The external size and volume of the feeder 101 of the conventional dish antenna make the space occupied by the conventional antenna larger. As shown in the second figure, the height from the top of the reflector 100 to the base is about 670 mm, and the top of the feeder 101 is about 670 mm. The length to the bottom of the inverted plate 100 is about 300 mm, which is not conducive to miniaturization of the dish antenna. [New content] M274661 Technical problem to be solved: The creation of this case is to solve the external size and volume of the feeder structure of the conventional dish antenna, occupy and hinder the reflective surface of the metal reflector, and reduce the radiation gain performance of the dish antenna. Problems, reduce the area and appearance volume of the feeder structure, effectively reduce the space occupied by the feeder, reduce the reflection surface of the metallic reflector disc blocked by the feeder, and can be applied to various dish antennas with limited feeder space, especially Small dish antenna. Technical means to solve the problem: This creation is a dish antenna feed structure, which includes a metal reflector and a feed, wherein the feed is bent into a gate shape from both sides of the metal plate in the same direction. The space appearance size of the sub is only about 10x10x30mm. The middle section of the sub is fixedly connected to the center of the metal reflecting plate with the gate-shaped opening of the sub facing away from the metal reflecting plate. The effect of technical means: The purpose and effect of the dish antenna feed structure of this creation is to bend the metal plate to form a feed with a Π-shaped opening, effectively reducing the area and space occupied by the feed, and improving the metal reflection. The reflection benefit of the disk makes the radiation gain of the dish antenna increase. The second purpose of this creation is to provide a dish antenna feeder structure with a space appearance size of only about 10x10x30mm, which can be effectively applied to various dish antennas with limited feeder space, and is particularly suitable for disk surface diameters of 100mm. Small size dish antenna with the following metal reflector.

In this embodiment, the diameter of the disk surface of the metal reflection disk (1) is about 100 mm; the feed (2) is a flat U-shaped metal plate with one end open. , The two sides of the metal plate are bent in the same direction to form a body-shaped door shape. In this embodiment, the spatial appearance of the three-dimensional door-shaped feeder (2) is about 10x10x30mm; the door of the feeder (2) The middle connecting portion (21) of the font is bent to form a convex piece (22), and the convex piece (22) is fixedly connected to the center of the metal reflection plate (1) and the three-dimensional door opening of the feeder (2) faces away from the metal The reflection disc (1) is connected to the three-dimensional door with the core wire (31) of the coaxial feed line (3) during implementation. Metal plate (2) on the open side of the feeder (u-shaped open end P3)-side, that is, the positive (+) pole, the network cable (32) of the coaxial feeder (3) is electrically connected to the metal plate of the feeder (2) The other side of the U-shaped open end (23) is the negative pole.
