Abstract

The present application provides an antenna system, including: M transmitting antenna pairs, the two transmitting antennas of each transmitting antenna pair in the M transmitting antenna pairs are symmetrically distributed on both sides of the same symmetry axis; N receiving antenna pairs, N The two receiving antennas of each receiving antenna pair in the receiving antenna pairs are symmetrically distributed on both sides of the symmetry axis; M branching devices correspond to the M transmitting antenna pairs; It is two transmission signals, which are respectively sent to the two transmitting antennas of the corresponding transmitting antenna pair; N combining devices correspond to the N receiving antenna pairs one by one; used to receive the two receiving antennas of the corresponding receiving antenna pair The two receiving signals of the two channels are synthesized into one receiving signal; wherein, the splitting device is a splitting device in the same direction, and the combining device is a reverse combining device; or, the splitting device is an anti-phase splitting device, and the combining device is a synchronous Combining circuit devices.

Description

technical field [0001] The present application relates to the technical field of wireless communication, and in particular to an antenna system. Background technique [0002] In mobile cellular communication systems, wireless local area network (English: Wireless Local Area Network, WLAN for short), fixed wireless access (English: Fixed Wireless Access, FWA for short) and other wireless communication systems, the base station (English: Base Station, referred to as: BS) or access point (English: Access Point, referred to as: AP), relay station (English: Relay Station, referred to as: RS) and user equipment (English: User Equipment, referred to as: UE) and other communication nodes usually have the ability to transmit their own signals and the ability to receive signals from other communication nodes. Because the attenuation of the wireless signal in the wireless channel is very large, compared with its own transmission signal, the signal from the communication peer reaches t...
