Abstract
An antenna apparatus includes a first radiation area, a phase adjustment area and a second radiation area. The first radiation area is disposed opposite to the second radiation area. The first radiation area is connected to one end of the phase adjustment area. The other end of the phase adjustment area is connected to the second radiation area. The first radiation area includes a feeding point of the antenna apparatus. The second radiation area includes a ground point of the antenna apparatus. The phase adjustment area is used to adjust a phase of a signal fed by the feeding point, to change a direction of a space electromagnetic field formed by an electromagnetic signal radiated by each of the first radiation area and the second radiation area.
