Example Embodiment

[0024] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] As mentioned before, for the AAS of the current wireless distributed base station system, the RRU is integrated with the antenna, and the RRU and the antenna are integrated into a whole for overall installation and maintenance. Makes field replacement and maintenance difficult.

[0026] For example, in some scenarios, if the antenna is a low-frequency antenna, such as an 800M to 900M antenna, the antenna length may reach 2m, or even 2...

Abstract

Embodiments of the invention provide an antenna apparatus, a base station and a communication system. The antenna apparatus comprises: an antenna part, an active part and a common part, wherein the antenna part comprises a common radome; the active part is connected with the antenna part and comprises at least one active module; the each active module comprises at least one antenna oscillator, a oscillator reflection plate and a phase shifter; the oscillator reflection plate and a phase shifter correspond with the each antenna oscillator; the oscillator reflection plate of the at least one active module is used for realizing an antenna function; the common part is connected with the active part and the antenna part and is shared by at least one active module in the active part; the common part comprises at least one common module. Through the above antenna apparatus, each radio frequency module can be flexibly configured so as to satisfy combination demands of different products. On-site replacing and maintenance operations can be further simplified.

Description

technical field [0001] Embodiments of the present invention relate to the field of mobile communication, and more specifically, to an antenna device, a base station, and a communication system. Background technique [0002] The early product architecture of the wireless distributed base station system is generally "RRU (Radio Remote Unit: radio remote unit) + antenna", in which the antenna is a passive unit. The above-mentioned "RRU+antenna" method generally has three connection implementation forms, which are: [0003] 1) The RRU is at the bottom of the tower, the antenna is on the tower, and the two are connected by cables; [0004] 2) The RRU is on the tower, very close to the antenna, installed at the bottom or behind the antenna, and connected by cables; [0005] 3) In the semi-integrated mode, the RRU is directly carried on the antenna, and is blindly inserted or connected to the antenna through a cable. [0006] For the semi-integration method of RRU and antenna, t...
