Disclosed are an antenna device for reducing antenna correlation of a multiple-input multiple-output (MIMO) system, and terminal, the antenna device comprising: a metal support plate inside a terminal, a main printed circuit board (PCB) and a sub-PCB supported by the metal support plate, a spring contact of a main antenna placed on the sub-PCB, a first spring contact of an auxiliary antenna and a second spring contact of the auxiliary antenna, respectively placed on the main PCB, and a radio frequency coaxial cable connecting the main PCB and the sub-PCB. The antenna device further comprises one or more slits in a non-PCB region of the metal plate, and positions and lengths of the slits are dependent on a wavelength associated with a frequency point of an antenna to be improved and a wiring position and a feeding position of the antenna in the entire terminal. |
