Abstract (en)
Provided are a terminal device antenna apparatus and an implementation method therefor, relating to the field of antennas. The method comprises: dividing off, on a metal ground of a terminal device main board, a fully enclosed non-metallic area configured to balance the electric current of the metal ground; disposing an antenna topology unit in the divided off fully enclosed non-metallic area; and the antenna topology unit generating an operating electric current by using a radio frequency signal provided by the terminal device main board, and coupling the operating electric current to the metal ground, so as to realize wideband impedance matching by means of local resonance multistage echo differential suppression.
