Dual-system phase shift combining module and separate electronic tilting antenna

Abstract

A dual-system phase shift combining module and a separate electronic tilting antenna are disclosed. The dual-system phase shift combining module comprises a system 1 phase shifter, a system 2 phase shifter, combiner PCBs, and a main feeder PCB. The system 1 phase shifter and the system 2 phase shifter work in two separate bands respectively. The system 1 phase shifter and the system 2 phase shifter share a profile cavity. The combiner PCBs and the main feeder PCB are in the same plane. The combiner PCBs are fixed on the surface of the profile cavity, the input ends are connected with the system 1 phase shifter and the system 2 phase shifter through shorting stubs, and the output ends are connected with an output port coaxial cable. The main feeder PCB is fixed on the surface of the profile cavity, the output end is connected with the system 1 phase shifter and the system 2 phase shifter through shorting stubs, and the input end is connected with a main feeder input coaxial cable. The phase shift combining module has the advantages of low cost, convenient assembly, low weight, excellent indicators and low profile, and can realize multi-path phase shift flexibly.

Description

technical field [0001] The invention relates to the field of mobile communication base station antennas, in particular to a phase-shifting and combining module applied to dual-system independent electrical adjustment antennas, and a corresponding independent electrical adjustment antenna. Background technique [0002] In recent years, mobile operators have increased investment in 4G network coverage year by year, thus forming a situation where 3G and 4G networks coexist. In order to save costs, operators hope to meet the needs of 3G and 4G service coverage at the same time at one site. In this way, The dual-system independent electronically adjustable antenna came into being. It not only supports both 3G and 4G standards, but also satisfies the needs of independent and flexible coverage of the above two networks. [0003] So far, the phase-shifting and combining schemes of dual-system independent electric-tunable antennas mainly include the following two types: 1. The phas...
