An antenna component and an unmanned aerial vehicle. The antenna component comprises an antenna unit capable of working in at least two bands and a direction guiding object, where the at least two bands comprise: a first band and a second band, and the direction guiding object is used for altering the radiating direction of the antenna unit on a first plane and the radiating direction on a second plane. This is used for optimizing and altering a radiating direction pattern of the antenna unit, has a simple implementation method, provides great effects, and satisfies demands of the unmanned aerial vehicle for antenna miniaturization and ease of installation.
