The invention provides a decoupling device. The decoupling device comprises a reflecting plate, a first radiation assembly, a second radiation assembly and a decoupling assembly. The first radiation assembly works in a first frequency band, and the first radiation assembly comprises a supporting column installed on one side of the reflecting plate and a radiation arm extending outwards from the supporting column. The second radiation assembly works in a second frequency band, and the second frequency band is higher than the first frequency band. The decoupling assembly comprises a conductive layer which sleeves the radiation arm and is spaced from the radiation arm, the conductive layer is provided with a plurality of radiation gaps, the electromagnetic waves of the first frequency band can pass through the radiation gaps, and the electromagnetic waves of the second frequency band can be blocked from passing through the radiation gaps. The decoupling assembly sleeves the radiation arm, allows low-frequency band electromagnetic wave signals to pass through and blocks high-frequency band electromagnetic signals, so that the influence of the first radiation assembly on the performance of the second radiation assembly is reduced.
Description
technical field [0001] The invention relates to the field of wireless communication base station antennas, in particular to a decoupling device and an array antenna. Background technique [0002] Base station (BS), that is, public mobile communication base station, is a form of radio station, which refers to a radio transceiver station that transmits information between mobile phone terminals through a mobile communication switching center in a limited radio coverage area. The base station is the basic unit that forms a cell in mobile communication, and completes the communication and management functions between the mobile communication network and mobile communication users. [0003] Base station antennas are an important part of wireless communication. With the rapid development of wireless communication, the demand for capacity has increased significantly, and multi-frequency antennas have become the mainstream of the market. Current multi-frequency antennas include low...
