1. An antenna assembly comprising:
a first antenna element comprising a first radiator;
a second antenna element comprising a second radiator, wherein a first gap is defined between one end of the second radiator and one end of the first radiator, and at least part of the second radiator is configured to be coupled to the first radiator through the first gap; and
a third antenna element comprising a third radiator, wherein a second gap is defined between the third radiator and the other end of the second radiator, and at least part of the third radiator is configured to be coupled to the second radiator through the second gap;
wherein an electromagnetic wave signal transmitted and received by the second antenna element under a coupling between the second radiator and the third radiator covers at least a global positioning system (GPS)-L1 band, a wireless fidelity (Wi-Fi) 2.4 GHz band, a long-term evolution middle-high band (LTE-MHB), and a new radio middle-high band (NR-MHB);
wherein the first radiator comprises a first ground end, a first coupling end, and a first feeding point disposed between the first ground end and the first coupling end, wherein the second radiator comprises a second coupling end and a coupling point disposed at one side of the second coupling end away from the first coupling end, and the first gap is defined between the second coupling end and the first coupling end, wherein part of the first radiator between the first feeding point and the first coupling end is configured to generate a second resonant mode under excitation of the first signal source;
wherein a length of the second radiator between the coupling point and the second coupling end is less than ¼ of a wavelength of an electromagnetic wave of a resonant frequency of the second resonant mode, and part of the second radiator between the coupling point and the second coupling end is configured to be in capacitive coupling with the first radiator.
