An antenna apparatus including a metal layer, a first planar antenna, a second planar antenna and a conducting wire is provided. The first planar antenna has a first ground terminal electrically connected to the metal layer. The second planar antenna has a second ground terminal electrically connected to the metal layer. The conducting wire is connected between the first planar antenna and the second planar antenna. In the whole operation, electromagnetic signals transmitted by the first planar antenna and the second planar antenna are in the same frequency band, and the coupling effect of the first planar antenna and the second planar antenna is reduced along with the formation of a current loop of the conducting wire.
