Problems solved by technology

[0004] For low frequencies, the beam width is very difficult to design. Due to the size limitation in the width direction, it is generally wide; while for high frequency bands, due to the influence of low frequency units, the beam width is very discrete, and the cross polarization index is difficul

Example Embodiment

[0024] See figure 1 , 2 In the illustrated embodiment, the multi-frequency dual-polarized antenna of the present invention includes a reflector 11, two low-frequency radiation units 15 arranged on the reflector 11, and eight high-frequency radiation units 14 adjacent to the low-frequency radiation unit 15 An isolation frame 12 is provided on the periphery of the high-frequency radiation unit 14, and two layers of suspension bars 13 and a suspension bar loading 17 are provided above the isolation frame 12. The high-frequency radiation unit 14 also includes a high-frequency parasitic radiator 16.

[0025] The two-layer suspension bar and the suspension bar are disconnected between loading, which can effectively avoid low-frequency resonance. In addition, the adjacent floating bars 13 and the lowermost floating bar and the isolation frame 12 are electrically coupled.

[0026] In this embodiment, the suspension bar 13 and the suspension bar loading 17 are metal boundaries. Each layer ...

Abstract

The invention provides a multi-frequency polarized antenna. The multi-frequency polarized antenna comprises a reflection plate, and the reflecting plate disposed at least one low frequency radiating element and the low frequency radiating unit adjacent to the at least one high frequency radiating element, the high-frequency radiation unit has a spacer periphery, with at least one suspension strip above the isolation box. The invention multi-frequency dual-polarized antenna with the new boundary structure, improve the consistency of the high-frequency pulse width, deformation reduced, cross-polarization improvement in high frequency high frequency cross polarization pattern has clearly improved.

Description

【Technical field】 [0001] The invention relates to the field of mobile communication base station antennas, in particular to a multi-frequency dual-polarized antenna. 【Background technique】 [0002] With the continuous development of mobile communication technology, the communication base station has put forward higher and higher requirements for the index requirements of the base station antenna, especially the gain, bandwidth characteristics, half-power angle fluctuation characteristics with frequency, and cross-polarization characteristics. [0003] Due to the current status of multi-mode mobile communication operations and the difficulty of site selection for base stations, multi-frequency base station antennas are the base station antenna products that are currently in great demand in the market. Multi-frequency antennas usually use a combination of high and low frequency antenna elements to achieve the required performance. However, due to the limitation of the volume ...
