Antenna and MIMO antenna

The invention relates to an antenna and an MIMO antenna, the antenna comprises two radiators and two central branches, and each radiator comprises at least two radiation units. The radiators are symmetrically distributed with the first coordinate axis as the symmetry axis, the two radiators are symmetrically distributed with the second coordinate axis as the symmetry axis, and the first coordinate axis is perpendicular to the second coordinate axis. One radiating body faces one end of the second coordinate axis and serves as a feed area of the antenna, and the other radiating body faces one end of the second coordinate axis and serves as a grounding area of the antenna. The two central branches are arranged along a first coordinate axis according to a preset spacing distance, and the two central branches are symmetrically distributed with a second coordinate axis as a symmetry axis. Each radiator corresponds to one central branch knot, the radiator is arranged at one end, facing the second coordinate axis, of
