Embodiment Construction

[0027] refer to Figure 1 to Figure 2 , a wide-bandwidth wide-beam dual-polarization antenna unit of the present invention includes two sets of two-polarized orthogonal dipole radiating units, and each group of dipole radiating units includes a pair of U-shaped radiating arms arranged symmetrically in the center 1. The U-shaped radiation arms 1 are all set on the corresponding baluns 4 . In the present invention, by changing the traditional design concept, the radiating arm is changed from the original linear, fan-shaped or square to the U-shaped form, so that the main lobe half-power angle of the antenna can be flexibly adjusted by adjusting the width of the U-shaped, so that the radiating unit is in the Under the same half-power angle, it has higher directivity, which lays a good foundation for realizing broadband and wide beam base station antennas.

[0028] As a preferred embodiment, the end of the U-shaped radiation arm 1 is bent inwards to increase the path of the curre...

Abstract

The invention discloses a broadband wide-beam dual-polarized antenna unit, which comprises two sets of polarized orthogonal dipole radiation units, wherein each set of dipole radiation units comprise a pair of central symmetrically arranged U-shaped radiating arms which are both arranged on a corresponding balancer. By changing the traditional design concept, the original linear, fan-shaped or square radiating arms are replaced by the U-shaped radiating arms, therefore flexibly adjusting the main lobe semi-power angle of the antenna by adjusting the U-shaped width, so as to obtain higher directivity of the radiation units under the same semi-power angle and provide good foundation for realizing broadband wide-beam base station antenna.

Description

technical field [0001] The invention relates to the field of mobile communication base station antennas, in particular to a dual-polarization antenna unit. Background technique [0002] With the development of mobile communication technology, the requirements for the indicators of dual-polarized base station antennas, especially the gain, bandwidth characteristics, half-power angle fluctuation characteristics with frequency, and cross-polarization characteristics, are increasingly demanding. [0003] The dual-polarized antenna unit mainly adopts the following realization forms: [0004] 1. Two pairs of dipoles are placed orthogonally to form an approximately square layout, such as the design disclosed in US Pat. No. 6,819,300B2. [0005] 2. Select a microstrip radiating unit to realize dual polarization through coupling or direct feeding, such as the microstrip dual-polarized antenna unit disclosed in Publication No. CN1822438A. [0006] 3. Two co-point, interleaved and or...
