1. An antenna apparatus, comprising:
a first radiator;
a second radiator, wherein a first coupling gap is provided between one end of the second radiator and the first radiator, and a first ground terminal is provided at the other end of the second radiator;
a first feeding source coupled to the first radiator, wherein the first feeding source is configured to provide a first excitation signal, wherein the first excitation signal is coupled to the second radiator through the first coupling gap, and is grounded through the first ground terminal, to excite the second radiator and at least part of the first radiator to jointly generate a first resonance;
a third radiator, wherein one end of the third radiator is connected to the first ground terminal, and the other end of the third radiator extends in a direction away from the second radiator, wherein the third radiator is provided with a second ground terminal spaced apart from the first ground terminal; and
a second feeding source, wherein the second feeding source is coupled to the third radiator on a side of the second ground terminal away from the first ground terminal, and the second feeding source is configured to provide a second excitation signal to excite a part of the third radiator located on the side of the second ground terminal away from the first ground terminal, to generate a second resonance.
