The disclosure provides an antenna, which comprises: a radiating unit, an antenna ground and a slot, wherein the radiating element is configured to be a curved metal wire to receive or radiate electromagnetic wave signals; the projection area of the radiating element serves as the antenna ground; and the antenna ground is provided with the slot which is configured to couple and resonate with the radiating element. The disclosure solves the problem that the antenna in relevant art can not meet the requirements of dual frequencies simultaneously, and thus achieves the effect of meeting the requirements of dual frequencies simultaneously.
