Problems solved by technology

For the former, when the antennas of each standard maintain a certain gain, the size of the antenna will be longer; for the latter, the antenna will become wider and there will be a strong coupling effect between different standards, resulting in antenna horizontal plane indicators such as wave width, alternating poles, etc. Compared with the deterioration of passive intermodulation and other indicators

Embodiment Construction

[0027] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0028] The present invention provides a multi-standard and multi-port fusion antenna, which includes a high-frequency 1-antenna array, a high-frequency 2-antenna array, and a low-frequency antenna array.

[0029] The high-frequency 1-antenna array includes 4 columns of dipoles, each column has n1 dipoles, and the high-frequency 1-antenna array supports horizontal plane beamforming;

[0030] The high-frequency 2-antenna array includes 1 column of dipoles, each column has n2 dipoles, and the high-frequency 2-antenna array does not support horizontal plane beamforming;

[0031] The low-frequency antenna array includes 1 column of dipoles, each column has n3 dipoles, and the low-frequency antenna array does not support horizontal plane beamforming;

[0032] Set reflector f1 and reflector f2, reflector f1 is higher than reflector f...

Abstract

The invention provides a multi-mode multi-port fusion antenna which includes a high-frequency (1) antenna array, a high-frequency (2) antenna array, and a low-frequency antenna array. The high-frequency (1) antenna array supports horizontal beam-forming. The high-frequency (2) antenna array does not support horizontal beam-forming. The low-frequency antenna array does not support horizontal beam-forming. A reflecting plate f1 and a reflecting plate f2 are arranged, and the reflecting plate f1 is higher than the reflecting plate f2. The high-frequency (1) antenna array is arranged on the reflecting plate f1. The high-frequency (2) antenna array is placed to the side of the high-frequency (1) antenna array. The oscillators of the low-frequency antenna array are all or partially embedded intothe high-frequency (1) antenna array, and the embedded part is not coplanar with the reflecting plate f2. The multi-mode multi-port fusion antenna provided by the invention has a very small windwardside on the premise that the performance is guaranteed. A miniaturized multi-port antenna is realized.

Description

technical field [0001] The invention relates to the technical field of fused antennas, in particular to an array technology for merging multiple standard antennas into miniaturized multi-port antennas. Background technique [0002] With the deep coverage of the 4G network, antenna resources are tight and site rental costs are high. In order to make more effective use of site resources and realize the common site and antenna feed of multiple antennas, operators at home and abroad have proposed to integrate the antennas required by multiple standards. Forming an array into one antenna becomes a miniaturized multi-port antenna. For example, China Mobile has proposed to integrate antennas of different systems such as 900MHz, 1800MHz, FA frequency band and D frequency band into one antenna to form a 900 / 1800 / FA / D 2288 independent electrical regulation fusion antenna. [0003] However, in traditional multi-standard multi-port base station antennas, antennas of different standards...
