Abstract
The present disclosure provides an antenna, and belongs to the field of radio frequency technology. The antenna provided by the present disclosure includes: a dielectric substrate, and a radiation patch and a waveguide feed structure, which are respectively disposed on two opposite sides of the dielectric substrate; an orthographic projection of a first transmission port of the waveguide feed structure on the dielectric substrate at least partially overlaps that of the radiation patch on the dielectric substrate; and the radiation patch is configured to convert a linearly polarized radiation signal transmitted via the first transmission port into a circularly polarized radiation signal. The antenna can realize conversion of the linearly polarized radiation signal into the circularly polarized radiation signal by adopting the radiation patch, so that a space occupied by the radiation patch can be reduced, thereby avoiding an increase in a thickness of the antenna.
