Multi-mode multi-port fusion antenna

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...

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
