Abstract: This application provides an antenna assembly. The antenna assembly includes at least a first antenna and a second antenna. The first antenna includes a first feed point and a first radiator connected thereto. The second antenna includes a second feed point and a second radiator connected thereto. There is a gap between the first radiator and the second radiator. An end of the second radiator close to the gap is provided with a first ground wire shared by the first antenna and the second antenna. An end of the second radiator away from the gap is provided with a second ground wire. Because currents excited by the first antenna and the second antenna are orthogonally complementary, crosstalk does not occur between the ground currents of the first antenna and the second antenna.
