Abstract:
The present disclosure provides a MIMO antenna device and a mobile communication device which comprises a metal shell and a metal piece, the metal shell comprises a metal back plate and a metal frame which are integrally formed, the metal frame surrounds the metal back plate, the metal piece and the metal shell enclose to form a metal cavity, the metal cavity comprises a battery region used to place a battery assembly and a non-battery region outside the battery region; a metal isolate wall is provided between the metal shell and the metal piece, the metal isolate wall partitions the metal cavity into a first cavity and a second cavity, the first cavity contains the battery region; a first feed unit feeds toward the first cavity to form a first antenna; and a second feed unit feeds toward the second cavity to form a second antenna. The MIMO antenna device and the mobile communication device in the present disclosure form a MIMO antenna device with high isolation through the first antenna and the second antenna, so as to achieve communication in the case of a full-metal outer shell.
