1. An antenna, comprising: a dielectric layer, and a first radiation patch, at least one second radiation patch and a feeding unit, which are on the dielectric layer, wherein the feeding unit is electrically connected to the first radiation patch, and each of the at least one second radiation patch is connected to the first radiation patch through at least one switch unit,
wherein the first radiation patch comprises a first side edge and a second side edge extending in a first direction and opposite to each other in a second direction; the at least one second radiation patch is connected to the second side edge of the first radiation patch through the at least one switch unit; the at least one second radiation patch comprises a plurality of second radiation patches, which are arranged side by side along the first direction,
wherein a side edge of the first radiation patch is provided with at least one first opening;
each of the at least one switch unit comprises a signal electrode and a membrane bridge; the signal electrode comprises a first end and a second end which are opposite to each other; the first end of the signal electrode is electrically connected to the second radiation patch, and an orthographic projection of the second end of the signal electrode on the dielectric layer is within an orthographic projection of one of the at least one first opening on the dielectric layer; the membrane bridge spans the one of the at least one first opening and is electrically connected to the first radiation patch; in the switch unit, an orthographic projection of the signal electrode on the dielectric layer overlaps an orthographic projection of the membrane bridge on the dielectric layer, and a first insulating layer is on a surface of the signal electrode facing the membrane bridge,
wherein each membrane bridge comprises a bridge deck, and a first connecting arm connected at a first end of the bridge deck and a second connecting arm connected at a second end of the bridge deck; an orthographic projection of the bridge deck on the dielectric layer spans an orthographic projection of the one of the at least one first openings on the dielectric layer; and the first connecting arm and the second connecting arm are each directly connected to the first radiation patch, and
widths of the bridge decks of the membrane bridges of the switch units connected to different second radiation patches monotonically increase or decrease along the first direction.
