Abstract

The embodiment of the present invention provides an antenna system and a base station. The antenna system of the present invention includes: a first antenna array for forming wide beam coverage and a second antenna array for forming narrow beam coverage; and the fist antenna array includes at least one row antenna, each row antenna provides at least a wide beam port, the second antenna array includes at least two rows antennas, and the second antenna array provides at least one narrow beam port. The embodiment of the present invention solves a problem that the small interval multi-row antennas can only provide narrow beam, and meets the requirement that the antenna system provides wide beam and narrow beam simultaneously.

Description

technical field

[0001] Embodiments of the present invention relate to communication technologies, and in particular to an antenna system and a base station. Background technique

[0002] With the development of communication technology, the layout of antennas faces the dual challenges of limited site space and small capacity. The antennas support multiple systems at the same time, such as supporting Global System For Mobile Communications (Global System For Mobile Communications, hereinafter referred to as GSM), Universal Mobile Telecommunications System (hereinafter referred to as UMTS) and Long Term Evolution (hereinafter referred to as LTE) systems have become an inevitable trend. The existing small-interval multi-column antenna layout technology realizes space division multiple access by splitting a single beam into multiple beams, and achieves the purpose of improving the capacity of the antenna.

[0003] However, this antenna layout technology can only provide narrow ...
