Abstract
An antenna includes: a dielectric layer having first and second surfaces opposite to each other; a radiating layer on the first surface, and having therein a slit; a first shielding layer on the second surface, and being electrically connected to the radiating layer; a first insulating layer on an upper side of the radiating layer; and a switch unit on an upper side of the first insulating layer, and corresponding to the slit. Each switch unit includes: a first electrode, a second insulating layer, a connecting portion, and a second electrode on the first insulating layer sequentially. Orthogonal projections of the first and second electrodes on the dielectric layer overlap each other. The connecting portion is connected to the second electrode to form a gap between the first and second electrodes. Orthogonal projections of the second electrode and a corresponding slit on the dielectric layer overlap each other.
