Abstract

An embodiment of the present invention provides a multi-sector MIMO active antenna system and communication equipment, including: N columns of dual-polarized antennas, wherein each column of dual-polarized antennas includes a column of antenna elements in a first polarization direction and a column of second poles An antenna unit in the first polarization direction, the antenna elements in the antenna unit in the first polarization direction are set to the first antenna downtilt and serve the first sector, and the antenna elements in the antenna unit in the second polarization direction are set to Downtilt for the second antenna and serve the second sector.

Description

technical field [0001] Embodiments of the present invention relate to antenna technology, and in particular to a multi-sector MIMO active antenna system and communication equipment. Background technique [0002] Multiple-Input Multiple-Output (MIMO) technology refers to the use of multiple transmitting antennas and receiving antennas at the transmitting end and receiving end, so that signals are transmitted and received through multiple antennas at the transmitting end and receiving end, thereby improving communication quality. MIMO technology can make full use of space resources, realize multiple transmission and multiple reception through multiple antennas, and can double the system channel capacity without increasing spectrum resources and antenna transmission power. Active Antenna System (AAS) is a radio frequency device that integrates an antenna and a radio frequency. On a physical site, the AAS can be regarded as an integration of a remote radio unit (Remote Radio U...
