1. An antenna assembly comprising:
a substrate;
a radiating patch disposed on the substrate; and
a matching structure, wherein the matching structure is configured to be electrically connected with a radio frequency (RF) signal circuit at one end of the matching structure, the matching structure comprises a first coupling piece at another end of the matching structure, the first coupling piece is in capacitive coupling with the radiating patch, and the first coupling piece is configured to feed a RF signal generated by the RF signal circuit into the radiating patch, to excite the radiating patch to generate a plurality of resonant modes, wherein at least one resonant mode in the plurality of resonant modes is generated by the capacitive coupling between the first coupling piece and the radiating patch.
