Phase shifting device, antenna and base station

Abstract

Provided is a phase shifting apparatus, comprising two phase shifters, and at least one combiner arranged between the two phase shifters. The combiner comprises an output end and two input ends, and each of the phase shifters comprises at least one output end; and one input end of the combiner is connected to an output end of one of the two phase shifters, and the other input end of the combiner is connected to an output end of the other phase shifter. The phase shifter comprises at least two successively connected U-shaped phase shifting circuits, and an output end of one U-shaped phase shifting circuit of any two adjacent U-shaped phase shifting circuits is respectively connected to an input end of the other U-shaped phase shifting circuit and an input end of the combiner. The phase shifting apparatus of the present invention uses fewer cables and solder joints, and has a smaller volume and a higher integration degree. Correspondingly, further provided are an antenna using the phase shifting apparatus, and a base station.

Description

technical field [0001] The invention relates to the field of mobile communication antennas, in particular to a phase shifting device, a corresponding antenna and a base station. Background technique [0002] With the development of mobile communications, multi-frequency antennas are playing an increasingly important role in network coverage. In order to reduce the windward area and facilitate network deployment, the miniaturization of multi-frequency antennas has become a research hotspot for major antenna manufacturers. One solution to the miniaturization of multi-frequency antennas is to use oscillator multiplexing technology, which can replace the traditional two independent arrays with broadband oscillator multiplexing. The broadband oscillator is connected to the combiner, and the two separated frequency bands are connected to the mobile Phase devices are connected to achieve the effect of independent electric regulation. The phase shifter is the core component of the ...

Problems solved by technology

[0003] In the prior art, it has become a trend to integrate the phase shifter and the combiner module. Usually, the combiner is fixed on the phase shifter, instead of being placed under the vibrator and fixed on the reflector like a conventional antenna. In fact, this solution can produce the phase shifter and combiner as one part, but it does not reduce the number of cables and solder joints, and the phase shifter has too many cables, which is a challenge for phase shifter wiring and welding
