Abstract

The invention discloses a novel fan-shaped beam scanning and reflecting array antenna, which is composed of two metal plates, a feed antenna, a waveguide reflecting array, a support part, a transitionpart and a mechanical adjusting part. Wherein the two metal plates are arranged opposite each other in parallel and form a hollow square box body with the support part, and the feed antenna is arranged in the middle of the rear direction between the two metal plates and the opening faces the front; The waveguide reflector array is arranged on the forward end face between two metal plates and is opposite to the feed antenna. The transition part extends from the edge of the metal plate where the feed antenna is located to the rear free space respectively. A mechanical adjust part is connected with that waveguide reflection array one by one and adjust the waveguide length respectively. The application of the antenna of the invention can obtain a fan-shaped beam and ultimately realize the horizontal scanning function, and the device has the advantages of small volume, reduced sidelobe, low manufacturing cost, concentrated energy and superior performance.

Description

technical field [0001] The invention relates to a novel fan-shaped beam scanning reflection array antenna, which belongs to the technical field of microwave antennas. Background technique [0002] With the rapid development of science and technology, especially communication, the means and equipment of long-distance wireless communication have made great progress. However, the existing scanning antennas usually have disadvantages such as large volume, high side lobe, complex structure, and high manufacturing cost. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art, provide a new type of fan-shaped beam scanning reflectarray antenna, and solve the problems of the existing scanning antennas such as large volume, complex structure, and high manufacturing cost. [0004] The technical solution of the present invention to achieve the above object is: a fan-shaped beam scanning reflectar...
