Description
Technical Field
The utility model belongs to the technical field of antennas, and particularly relates to an ultra-wide beam linear polarization antenna.
Background
In order to achieve a wider signal coverage in a mobile communication system, an antenna having ultra-wide beam characteristics on both the E-plane and the H-plane is required. At present, the beam width of the existing linear polarization antenna with the E surface and the H surface capable of realizing wider beams is 110 degrees on the E surface and 110 degrees on the H surface, but for some scenes with wider coverage requirements, the beam width of the E surface and the beam width of the H surface can be simultaneously larger than 110 degrees, and the existing traditional antenna can not be realized basically.
Although the electric dipole radiating element is configured by loading a metal through hole on the outer side of the horn antenna with an open end, a wide beam of about 110 ° is realized on both the E-plane and the H-plane, but this method cannot realize a wider beam width.
