Problems solved by technology

For the LTE system, the number of antennas is large because it needs to adopt MIMO technology. If the number of antennas needs to be doubled, it will bring a greater burden to the construction and transformation of the antenna feeder system.

Abstract

The invention discloses multiple-input-multiple-output (MIMO) eight antennae and a base station and relates to the field of mobile communication. The MIMO eight antennae include an upper antenna array and a lower antenna array. Two dual-polarization antennae are arranged in each of the upper and lower antenna arrays. The upper and lower antenna arrays adopt an up-down vertical isolation mode. The inclined angle of normal directions of the upper and lower antenna arrays is 60 degrees. The two dual-polarization antennae in the upper / lower antenna array are capable of forming 33-degree horizontal width wave beams at two different polarization directions. The 33-degree horizontal width wave beams formed by the upper / lower antenna array are vertical to the plane of the upper / lower antenna array and the wave beam direction is the normal direction of the plane of the upper / lower antenna array. The invention proposes an MIM-eight-antenna design scheme which is based on the vertical isolation mode and compatible with three-sector and six-sector configurations so that an antenna device can be used under both of a three-sector configuration and a six-sector configuration and thus the antenna device does not need to be replaced.

Description

technical field [0001] The present invention relates to the field of mobile communications, in particular to a multiple input and multiple output (Multiple Input and Multiple Output, MIMO for short) eight-antenna and base station compatible with 3-sector and 6-sector system configurations based on a vertical isolation mode. Background technique [0002] At present, the mobile communication network has developed to the third generation (referred to as 3G). 3G networks have been deployed and commercialized on a large scale worldwide. With the continuous popularization and promotion of data services and mobile Internet, the International Communication Standards Organization is formulating long-term Evolution (Long Term Evolution, referred to as LTE) and the fourth generation (referred to as 4G) and other technical standards to meet the continuous development of network technology and service capabilities. Since MIMO technology can make full use of independent spatial propagatio...
