Flexible ultra-wideband MIMO antenna

The invention provides a flexible ultra-wideband MIMO antenna, which is used for improving the isolation degree of the ultra-wideband MIMO antenna, expanding the frequency band range of the antenna, comprising a flexible thin film dielectric plate (1), a radiation unit (2) printed on the upper surface of the dielectric plate and a radiation floor (3) printed on the lower surface of the dielectricplate. The radiating unit (2) adopts a center symmetrical structure composed of four first radiating patches (21), wherein the first radiating patch (21) is formed by splicing a plurality of circulararc curves, and each first radiating patch (21) is connected with a feed line (4); the radiation floor (3) adopts a centrally symmetrical structure consisting of four second radiation patches (31), wherein the second radiation patch (31) is formed by splicing a first rectangular patch (311) and a second rectangular patch (312). The invention has the advantages of small volume, high isolation degree, wide frequency band ran
