1. An antenna, comprising:
a dielectric substrate;
a first radiating element and a second radiating element which are arranged on the dielectric substrate, wherein the second radiating element is arranged around the first radiating element and is of an open-loop structure, and at least one first groove is arranged in at least one edge of the first radiating element;
the antenna further comprises:
at least one switching element, each switching element corresponds to one of the at least one first groove; the switching element comprises a membrane bridge and a signal electrode, and the signal electrode is arranged on the dielectric substrate, coupled to the second radiating element and insulated from the first radiating element; the membrane bridge is arranged on a side of the first radiating element away from the dielectric substrate, each membrane bridge crosses one of the at least one first groove, and at least part of the signal electrode is positioned in a space defined by the membrane bridge and the first groove,
wherein the second radiating element has at least one through slot disposed therein, the through slot divides the second radiating element into two parts, wherein each part of the second radiating element is disposed in correspondence with at least one switching element, and the two parts of the second radiating element are respectively in correspondence with different numbers of switching elements.
