A kind of antenna and antenna device

Abstract

The invention discloses an antenna. The antenna comprises a first antenna module, a second antenna module and a third antenna module, wherein air gaps are formed among the first antenna module, the second antenna module and the third antenna module, the first antenna module comprises a parasitic patch and a first PCB, the second antenna module comprises a second PCB, a first control patch, a second control patch and a main radiation patch, a first feeding point and a second feeding point are arranged on the main radiation patch, groove bodies are arranged on both of the first control patch andthe second control patch, radio-frequency switches are arranged in the groove bodies, the third antenna module comprises a floor layer, a third PCB and a switch pin wire, and the switch pin wire is used for connecting the radio-frequency switches and a mainboard so that the mainboard outputs a control signal to control working conditions of the radio-frequency switches. The invention also discloses antenna equipment. With the adoption of the antenna disclosed by the embodiment, switching of a directional diagram in a horizontal direction can be achieved under horizontal and vertical polarization, the antenna is small in size, and the radio-frequency switches can be automatically controlled.

Description

technical field [0001] The present invention relates to the technical field of antennas, in particular to an antenna and antenna equipment. Background technique [0002] With the development of modern science and technology, all kinds of wireless systems such as wireless communication and military / civilian radar use radio waves to work, and the reception and transmission of radio waves are completed by antennas. At present, one of the important directions for the development of various integrated information systems is: large capacity, multi-function, ultra-broadband. Obviously, by increasing system capacity, increasing system functions, and expanding system bandwidth, on the one hand, the increasing actual demand can be met, and on the other hand, the system cost can be reduced. Based on the above requirements, a concept of "reconfigurable antenna" is proposed. The research on reconfigurable antenna aims to enable the antenna to be reconfigured in real time according to th...

Problems solved by technology

[0004] The antennas in the prior art are bulky, and the radiation corresponding to the 2.4G frequency band requires the combination of the above-mentioned multiple antennas, which requires a PCB board of about 240mm*240mm in total, which is not suitable for miniaturized outdoor AP products; when the horizontal polarization works, the direction The pattern can only be changed in the horizontal direction (phi=0°), and the pattern can only be changed in the vertical direction (phi=90°) when working with vertical polarization. There are great limitations in the two working modes; switch processing Manual processing with copper foil, unable to open and close intelligently
