1. An antenna comprising:
a dielectric substrate comprising a first surface and a second surface;
a first radiation unit arranged on the first surface;
a second radiation unit extended from the second surface to the first surface; wherein the second radiation unit comprises a ground portion and a first radiation portion, a part of the second radiation unit arranged on the first surface is used as the first radiation portion, and the first radiation portion and the first radiation unit are adjacent and spaced; and
a feed portion configured to feed current to the first radiation unit, the first radiation unit excited a first radiation frequency band, the current flowing through the first radiation unit further coupled and fed into the first radiation portion, and the first radiation portion excited a second radiation frequency band;
wherein the first radiation unit comprises a second radiation portion and a third radiation portion, the second radiation portion is connected to the third radiation portion, the second radiation portion is a right-angled trapezoid, and the third radiation portion is rectangular, a length of a bottom edge of the second radiation portion is less than a length of the third radiation portion, a right-angle side edge of the second radiation portion is flush with one end of the third radiation portion.
