Abstract: An antenna apparatus includes a ground plate, a radiator, and a signal source. The radiator is disposed on the ground plate. The signal source is configured to feed an electromagnetic wave signal of a first frequency band into the radiator. A first slot and a second slot are disposed on the ground plate. Both slots are closed slots and surround the radiator, and are used to restrain current distribution on the ground plate.

Abstract: An antenna system includes a first antenna, a second antenna, and a tuning stub, where the first antenna and the second antenna have a same first operating frequency band or similar first operating frequency bands. The tuning stub is electrically connected to the first antenna, and the tuning stub is configured to adjust an equivalent current path of the first antenna, so that a connection line between a projection point of a maximum equivalent current point of the first antenna and a projection point of a maximum equivalent current point of the second antenna on a first plane tends to be more perpendicular to a projection of the equivalent current path of the first antenna or of the second antenna on the first plane; or the equivalent current path of the first antenna and of the second antenna tend to be more perpendicular to each other.
