Abstract

The invention discloses an ultra-wideband and wide beam bipolar antenna unit. The unit comprises two groups of bipolarized orthogonal dipole radiating units, wherein each dipole radiating unit comprises a pair of Baluns and a pair of U-shaped radiating oscillators respectively arranged on the Baluns; the U-shaped radiating oscillators are arranged centro-symmetrically; and each U-shaped radiating oscillator comprises two horizontally bent branches, two vertically bent branches and an I-shaped branch, the horizontally bent branches are arranged on the outer sides of the tail ends of the radiating arms of the U-shaped radiating oscillator, the vertically bent branches are arranged at the tail ends of the radiating arms of the U-shaped radiating oscillator, are vertical to the tail end of the U-shaped radiating oscillator, and extend along the axial direction, and the I-shaped branch is arranged between the two radiating arms of the U-shaped radiating oscillator. In the way that the horizontally bent branches, the vertically bent branches and the I-shaped branches are loaded on the U-shaped radiating oscillators, the U-shaped radiating oscillators can superpose radiation in multiple resonant modes, so that bandwidth is greatly increased, and the bandwidth of an antenna can be widened by the unit.

Description

technical field [0001] The invention relates to the field of mobile communication base station antennas, in particular to an ultra-wide bandwidth beam dual-polarization antenna unit. Background technique [0002] With the development of mobile communication technology, communication base stations have put forward higher and higher requirements for the indicators of dual-polarized antenna units, especially in terms of gain, bandwidth characteristics, and half-power angle fluctuation characteristics with frequency. [0003] At present, a widely used dual-polarized antenna unit with adjustable beam width, such as figure 1 As shown, including: two sets of dipole radiating units with orthogonal polarization; [0004] Wherein, each group of dipole radiating units includes: a pair of baluns and a pair of U-shaped radiating arms arranged on the pair of baluns; and the pair of U-shaped radiating arms are arranged symmetrically about the center. [0005] The U-shaped radiating arm i...
