Abstract

The invention belongs to the technical field of antennas, and provides a wide beam antenna. The antenna comprises a reflection base, an antenna structural member, a radio frequency connector and special structures with a preset height, wherein the special structures are any one of a cylinder structure, a plate-shaped structure and a cylinder structure; the antenna structural member is fixed at a central position of a front surface of the reflection base; the radio frequency connector is fixed at the central position of a back surface of the reflection base, and a probe of the radio frequency connector penetrates through the reflection base and is connected with the antenna structural member; and the special structures are fixed to the front surface of the reflection base and arranged on aperiphery of the antenna structural member, and the special structures in each direction are spaced from a center point of the antenna structural member by a preset distance. In the invention, the special structures are loaded around the antenna structural member, a beam width of the antenna can be broadened, and a low elevation gain of the antenna is improved.

Description

technical field [0001] The invention belongs to the technical field of antennas, and more specifically relates to a wide-beam antenna. Background technique [0002] With the advancement of science and technology, the technology of satellite communication is becoming more and more sophisticated, and the requirements for antennas are also getting higher and higher. There are various traditional antenna structures, but they have the disadvantages of narrow beam width and low gain at low elevation angles. Contents of the invention [0003] In view of this, the present invention provides a wide-beam antenna, aiming at solving the problems of narrow beam and low gain at low elevation angles in the prior art. [0004] The first aspect of the embodiments of the present invention provides a wide-beam antenna, including: a reflection base, an antenna structure, a radio frequency connector, and a plurality of cylindrical structures with preset heights; [0005] The antenna structur...
