Abstract

The invention discloses a sugar shovel type fan-shaped beam horizontal scanning antenna, which comprises two metal plates (1), a horn antenna (2), a reflection surface (3), a transition structure (4) and a connection structure (5); The connecting structure (5) includes a first connecting portion formed by connecting one side of the horn antenna (2) to one end of the reflecting surface (3), and connecting the other side of the horn antenna (2) to the reflecting surface (3) The second connection part formed by the side wall of the metal plate (1) where the other end of to the metal plate (1) where the radiation opening is located, and the other end of the transition structure (4) extends toward the free space. The invention can obtain fan-shaped beams and finally realize the horizontal scanning function, can prevent energy leakage, and make the energy utilization rate higher and the side lobe lower, and the antenna gain is higher, the energy is more concentrated, and the performance is better.

Description

technical field [0001] The invention relates to a sugar shovel-shaped fan-shaped beam horizontal scanning antenna, which belongs to the technical field of radio frequency antennas. Background technique [0002] The sugar shovel fan-shaped beam horizontal scanning antenna enables the whole system to realize fan-shaped beam and finally realize the horizontal scanning function, and has the characteristics of high gain, low sidelobe, concentrated energy and superior performance, and is widely used in radar and remote microwave Communication systems and other fields. [0003] At present, the existing scanning antennas usually have the disadvantages of large energy leakage, low energy utilization rate, high side lobes, and high processing precision requirements. Contents of the invention [0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art, and provide a sugar shovel-shaped fan-shaped beam horizontal scanning ante...
