Abstract
An antenna structure, a detection apparatus, and a terminal device are provided, and relate to the field of millimeter-wave radar technologies, to reduce a profile height of the antenna structure. The antenna structure includes a radome and an antenna, and a first surface of the radome is in contact with a first surface of the antenna. A radiation portion is provided on the first surface of the antenna, a first groove is provided in the first surface of the radome, and the first groove and the radiation portion form a first cavity.
