1. An antenna apparatus, wherein the antenna apparatus comprises a strip radiator, and a feed point and a ground point are disposed on the strip radiator;
the ground point is connected to a grounding stub, and the grounding stub is configured for grounding of the strip radiator, and a sum of a distance between the feed point and the ground point and a length of the grounding stub is less than a quarter of a first wavelength,
wherein a first current and a second current with different frequencies are distributed on the strip radiator, directions of the first current on two sides of the feed point are opposite, and directions of the second current on the two sides of the feed point are the same, the first wavelength corresponds to a frequency of the first current.
