1. An antenna, comprising a dielectric substrate, and a first radiation patch, at least one second radiation patch and a feed unit disposed on the dielectric substrate, wherein the feed unit is electrically connected with the first radiation patch; a switch unit is arranged between each second radiation patch and the first radiation patch;
the switch unit comprises a driving electrode and a membrane bridge which are arranged on the dielectric substrate, a bridge deck of the membrane bridge is suspended on a side, away from the dielectric substrate, of the driving electrode, and an insulating layer covers on a side, close to the bridge deck of the membrane bridge, of the driving electrode; the switch unit is configured to control whether or not the membrane bridge allows a current between the first radiation patch and the second radiation patch by controlling a voltage applied to the driving electrode,
wherein an edge of the first radiation patch is provided with at least one first notch therein, and
wherein orthographic projections of the second radiation patch and the first notch on the dielectric substrate are not overlapped with each other.
