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 multi-port fusion antenna, including 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 rows of dipoles, each with n1 dipoles, and the high-frequency 1 antenna array supports horizontal plane beamforming;

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

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

[0032] The reflecting plate f1 and the reflecting plate f2 are arranged, and the reflecting plate f1 is higher th...

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 present invention relates to the technical field of fusion antennas, in particular to an array technology for fusing multiple standard antennas into a miniaturized multi-port antenna. Background technique [0002] With the in-depth coverage of 4G networks, antenna resources are in short supply, and site rental costs are high. In order to more effectively use site resources and achieve co-site and antenna feed for multiple antennas, domestic and foreign operators propose to integrate antennas with multiple standards. Array into one antenna becomes a miniaturized multi-port antenna. For example, China Mobile proposes to combine the 900MHz, 1800MHz, FA band and D band antennas into a single antenna to form a 900 / 1800 / FA / D 2288 independent electric tuning fusion antenna. [0003] However, in traditional multi-standard multi-port base station antennas, antennas of different standards are generally placed side by side or side by side. For the former, the ante...
