Abstract: Embodiments of the present invention provide an antenna apparatus. The antenna apparatus includes multiple antennas, a switching unit, a grounding layer, connecting lines and a dielectric substrate. The antennas are configured to transmit and receive electromagnetic waves. The connecting lines are configured to connect the switching unit and the antennas. The switching unit is configured to selectively feed signals to the antennas through the connecting lines. The grounding layer serves as a reference of zero potential, and by setting the shape or size of the grounding layer and the distance from the grounding layer to the antennas, the grounding layer is further configured to restrain a transmitting direction of the electromagnetic waves transmitted by the antennas. The dielectric substrate is configured to allow the grounding layer to be printed thereon, and the dielectric substrate is further configured to allow the antennas, the switching unit and the connecting lines.
