A multimode broadband antenna module and a wireless terminal are provided. The multimode broadband antenna module includes a printed circuit board and an antenna body, where the antenna body includes a first radiator and a second radiator that are electrically connected to the printed circuit board, where the first radiator includes a connection portion, a low frequency portion, and a high frequency portion, the second radiator includes a grounding portion, a low frequency portion, and a high frequency portion, and a first predetermined distance exists between the low frequency portion of the first radiator and the low frequency portion of the second radiator, and a second predetermined distance exists between the high frequency portion of the first radiator and the high frequency portion of the second radiator, so as to form a coupling capacitance effect between the first radiator and the second radiator.
