Abstract: An antenna device and a beam direction adjustment method are provided. The antenna device includes an antenna element, a metal element, and a substrate. The antenna element and the metal element are separately disposed on the substrate at a preset distance. A ground point of the metal element is fastened on a pad of the substrate, and the ground point is on a side of the metal element close to the antenna element. A first reverse current opposite to an antenna current generated by the antenna element is obtained through coupling on the side of the metal element close to the antenna element, and a second reverse current opposite to a substrate current generated by the substrate is obtained through coupling at a lower part of the metal element that is in contact with the substrate.

Abstract: A wearable device includes: a metal middle cover, a metal bottom cover, a printed circuit board PCB, and a gap. The metal middle cover encircles the wearable device for a whole circle and serves as an exterior of the wearable device. The metal bottom cover is located under the metal middle cover and serves as a rear cover of the wearable device. The gap with a preset width exists between the metal middle cover and the metal bottom cover, and serves as a slot antenna of the wearable device. The PCB is in an inner side of the metal middle cover, and is located above the metal bottom cover. The PCB is electrically connected to the metal middle cover by using a feed point, and feeds power to the metal middle cover.
