The invention provides a multiple input multiple output antenna device and mobile communication equipment. The multiple input multiple output antenna device comprises a first antenna and a second antenna, wherein the first antenna comprises a metal shell and a metal sheet, the metal shell comprises a metal back plate and a metal frame which are integrally molded, and the metal frame surrounds themetal back plate; the metal sheet and the metal shell formed an unclosed cavity in an enclosing manner, the periphery of the metal sheet and the metal frame are provided with at least one gap and at least one opening part therebetween, and the unclosed cavity is subjected to direct feeding or coupled feeding through a feed unit; and the second antenna is located at the opening part and fed througha second feed unit. According to the multiple input multiple output antenna device and the mobile communication equipment provided by the invention, a high-isolation MIMO antenna device is formed through the first antenna and the second antenna, thereby achieving communication in the case of a full metal shell.
Description
technical field [0001] The invention relates to the field of antennas, in particular to a multiple-input multiple-output antenna device and mobile communication equipment. Background technique [0002] In the current wireless communication equipment, all-metal shells are increasingly used due to their advantages such as beautiful appearance, high structural strength, and excellent thermal conductivity. Wireless communication equipment generally transmits electromagnetic signals through an antenna device, but the antenna device is easily shielded and interfered by a metal casing when receiving and sending signals. [0003] In order to overcome signal shielding and interference, the housing of a wireless communication device in the prior art is usually composed of two parts, that is, a metal part and a non-metal space. The antenna radiation unit is designed in the non-metal space of the casing, so that the radiation of the antenna is not shielded by the metal part or the infl...
