1. An antenna assembly comprising:
a first antenna element configured to generate a plurality of first resonant modes to transmit and receive an electromagnetic wave signal of a first band, wherein the first antenna element comprises a first radiator; and
a second antenna element configured to generate at least one second resonant mode to transmit and receive an electromagnetic wave signal of a second band, wherein a maximum frequency of the second band is less than a minimum frequency of the first band, the second antenna element comprises a second radiator, a first gap is defined between the second radiator and the first radiator, and the second radiator is configured to be in capacitive coupling with the first radiator through the first gap;
wherein at least one of the plurality of first resonant modes is formed through the capacitive coupling between the first radiator and the second radiator;
wherein:
the first antenna element further comprises a first signal source;
the first radiator comprises a first ground end, a first feeding point, and a first coupling end, wherein the first ground end is configured to be grounded, the first feeding point is disposed between the first ground end and the first coupling end, the first feeding point is electrically connected to the first signal source, and the first coupling end is adjacent to the first gap; and
the second radiator comprises a second coupling end and a first coupling point, wherein the first gap is defined between the second coupling end and the first coupling end, the first coupling point is disposed at one side of the second coupling end away from the first coupling end, and the first coupling point is configured to be grounded.
