Abstract

The invention belongs to the technical field of mobile communication antenna equipment, and discloses a low-frequency antenna oscillator and a base station antenna. The low-frequency antenna oscillator comprises an oscillator PCB board, Balun PCB boards and a feeding PCB board; two pairs of dipoles are arranged on the oscillator PCB board, and the oscillator PCB board is used for forming a radiation face; each pair of dipoles comprises two opposed dipoles and polarization directions of the two dipoles are perpendicular mutually; each dipole comprises two radiation arms; four Balun PCB boards are provided in total; a parallel line Balun is arranged on each Balun PCB board; each parallel line Balun is used for carrying out feeding on one dipole; two feeding lines are arranged on the feedingPCB board; each Balun PCB board is respectively connected with the oscillator PCB board and the feeding PCB board; and the base station antenna comprises a feeding network, a signal input port and thelow-frequency antenna oscillator. The invention solves problems of relatively serious structural deformation, large oscillator size, heavy weight and complex assembling and welding of an antenna oscillator in the prior art.

Description

technical field [0001] The invention relates to the technical field of mobile communication antenna equipment, in particular to a low-frequency antenna vibrator and a base station antenna. Background technique [0002] The antenna dipole unit is a relatively important component in the base station antenna of the mobile communication base station system. The vibrator unit is based on the excitation principle of electromagnetic waves, and the vibrator is made into a resonator in terms of physical size, so as to achieve the purpose of transmitting and receiving electromagnetic waves of specific frequencies. [0003] figure 1 It is a schematic structural diagram of a low-frequency cast aluminum vibrator supporting high and low frequency nested installation in the prior art. In the prior art, two pairs of dipoles are connected into one body through a metal ring at the base of the balun, and the radiating arms of the radiating surface are separated from each other, which easily ...
