Transmission system and base station antenna therefor

Abstract

The invention discloses a transmission system and a base station antenna therefor. The transmission system comprises an RCU module and a transmission module, wherein the RCU module comprises an RCU housing, a drive mechanism and a first guide mechanism, wherein the drive mechanism is assembled in the RCU housing; the first guide mechanism is arranged on the RCU housing; a first transmission interface is arranged at an output end of the drive mechanism; the transmission module comprises a mounting frame, a transmission mechanism and a second guide mechanism; the transmission mechanism is assembled on the mounting frame and is used for adjusting a phase shifter to decline downwards; the second guide mechanism is arranged on the mounting frame; a second transmission interface is arranged at an input end of the transmission mechanism; the first guide mechanism is inserted into the second guide mechanism, so that the first transmission interface and the second transmission interface are in transmission fit and the RCU module and the transmission module are fixed by each other. Through the implementation method, the transmission system is simple in structure and small in occupied space; and the RCU module can be relatively well protected, so that improvement of the transmission accuracy is facilitated.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a transmission system and a base station antenna thereof. Background technique [0002] The mobile communication system is a combination of wired and wireless. It is a complex in which the mobile network connects the mobile station with the base station through the air interface (antenna) within its coverage area, and then connects with the mobile switch. Therefore, the antenna is very important for mobile communication. For the network, it plays a decisive role. If the antenna selection (type, location) is not good or the antenna parameters are not set properly, it will directly affect the operation quality of the entire mobile communication network. Especially in areas with a large number of base stations, small station distances, and high traffic areas with a large number of carrier frequencies, coupled with the multiple reflections and occlusions of radio waves c...

Problems solved by technology

[0004] However, there are many deficiencies in the prior art methods for the design of the transmission system. The RCU module of the existing transmission system is usually designed outside the electronically adjustable antenna. This design not only greatly increases the occupied space outside the antenna, but also the modules of the transmission system The connection is complicated, the transmission accuracy is low, and the RCU module cannot be well protected
