Antenna device and wireless communication equipment

Abstract

The invention relates to an antenna device and wireless communication equipment. The antenna device includes a first antenna unit, a second antenna unit, an isolation unit, and a circuit substrate. The first antenna unit includes a matrix and a first radiating part wound on the surface of the matrix. The circuit substrate includes a first conductive plate and a second conductive plate. One end ofthe first conductive plate is connected with the first radiating part, and the second conductive plate is grounded. The second antenna unit includes a second radiating part arranged on the surface ofthe circuit substrate. Part of the second radiating part is parallel and adjacent to the second conductive plate. The isolation unit is arranged between the first antenna unit and the second antenna unit and connected with the second conductive plate in order to isolate at least part of the first antenna unit and the second antenna unit. The isolation unit weakens the interference between the twoantenna units, and optimizes the signal receiving capability of the antenna device. Thus, the spacing between the antenna units is reduced and the space occupied by the antenna device is saved while better signals are obtained.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to an antenna device and wireless communication equipment. Background technique [0002] Antenna devices are important components in wireless communication equipment. With the development of multi-function and miniaturization of wireless communication equipment, the miniaturization requirements for antenna devices are gradually increasing. In order to realize the multi-function of the device, the antenna device often needs to support multiple signals at the same time, such as positioning signals, 4G signals, Bluetooth signals, Wi-Fi signals, etc., so the same antenna device may include multiple antenna units that support different frequency bands. However, with the continuous miniaturization of equipment, the space for an antenna device inside the equipment is getting smaller and smaller. Therefore, the configuration of each antenna unit is often very close, and it is easy to i...
