1. An antenna comprising a first radiation part, a second radiation part, a feed part, and a ground part,
wherein the first radiation part comprises a first radiator, the second radiation part comprises a second radiator, the first radiator connects to a first side of the feed part and protrudes upwardly from the first side of the feed part, the second radiator connects to a second side of the feed part and protrudes upward from the second side of the feed part, the first side of the feed part is arranged relative to the second side of the feed part, wherein a height difference between the first radiator and the second radiator in a first direction is set within a preset range, and by setting the height difference between the first radiator and the second radiator in the first direction with preset range, a radiation interference between the first radiator and the second radiator is reduced, thus improving the radiation efficiency of the antenna, the first direction is perpendicular to a plane where the feed part is located, and
the ground part is arranged vertically on a side of the first radiator, wherein a preset interval exists between the ground part and the feed part in a second direction that is perpendicular to the first direction, and an input impedance matching of the antenna is adjusted by adjusting the preset interval between the ground part and the feed part, and the ground part comprises an open slot.
