Low-frequency radiation unit

Abstract

The invention discloses a low-frequency radiation unit, which comprises multiple Baluns, multiple dipoles, a base, multiple positioning clips, multiple positioning clamps, a radiation unit pad and a reflection plate, wherein each dipole comprises a first radiation arm and a second radiation arm, the tail end of the first radiation arm is provided with a first loading section, and the tail end of the second radiation arm is provided with a second loading section; the first radiation arm and the second radiation arm are connected with the top part of the base through the Baluns; each positioning clamp is used for connecting the first radiation arm and the second radiation arm in each dipole; the positioning clip is used for connecting a first radiation arm and an adjacent second radiation arm which belong to different dipoles; the radiation unit pad is connected with the bottom part of the base and the reflection plate; the radiation unit pad comprises an insulation body; the top part of the insulation body is provided with a radiation unit connector for connecting the base; and the bottom part of the insulation body is also provided with a reflection plate connector for connecting the reflection plate. Consistency of each low-frequency radiation unit can be ensured, and the antenna performance is thus improved.

Description

technical field [0001] The invention relates to the technical field of antenna structures, in particular to a low-frequency radiation unit. Background technique [0002] At present, 800 / 900MHz radiating units are used in a large number of arrays in dual-polarized base station antennas. The performance of the antenna is determined by the parameters of the standing wave, isolation, and third-order intermodulation of the antenna. The reason for affecting these parameters mainly comes from the low-frequency radiating unit. Structure. [0003] In the process of implementing the present invention, the inventor found that the existing low-frequency radiation unit has the following disadvantages: [0004] The connection reliability of the low-frequency radiation unit is low, and the anti-deformation ability is poor, which leads to different degrees of deformation and loose parts of the low-frequency radiation unit during processing, transportation, installation or storage, so that ...
