Abstract

The invention provides a broad-band dual polarization base station antenna unit which is used to solve problems that structural stability is poor and a technology is complex in an existing dual polarization base station antenna unit. The unit comprises radiators (1), a first feed balun (2), a second feed balun (3), a pedestal (4) and a reflecting plate (5). The first feed balun (2) and the second feed balun (3) are mutually orthogonal. Top ends of the two feed baluns (2, 3) are provided with the radiators (1) which are vertical to the top ends and bottom ends are connected to radio frequency cables (6) respectively. The pedestal (4) is fixed to the reflecting plate (5). Tops and bottoms of the first feed balun (2) and the second feed balun (3) are provided with two rectangular embossments respectively and the rectangular embossments are used for connecting the radiators (1) and the pedestal (4). The unit possesses advantages that the structure is simple; processing is convenient; a frequency band is wide; an isolation degree is high and a directional diagram is good. And the unit can be used for a miniaturization base station antenna in a new generation communication system.

Description

technical field [0001] The invention belongs to the technical field of mobile communication, and relates to a broadband dual-polarization base station antenna unit, in particular to a broadband dual-polarization base station antenna unit with simple structure and convenient processing, which can be used for mobile communication base station antenna arrays. Background technique [0002] The base station refers to the radio transceiver station that transmits information between the mobile communication switching center and the mobile terminal in a certain radio coverage area. Among them, the antenna, as one of the most important components in the base station, is mainly responsible for the communication equipment. Electrical signals and space radiated electromagnetic waves are converted. Base station antenna design is very important in base station applications. Base station antennas can be divided into single-polarization and dual-polarization base station antennas according...
