Abstract
A directional antenna including a ground plane, a feeding element and a radiating element is provided. The feeding element is adjacent to the ground plane and includes a feeding point. A coupling gap is formed between the radiating element and the feeding element, and the radiating element includes a coupling point. Both the coupling point of the radiating element and the feeding point of the feeding element are at the perpendicular line of a ground plane. Further, a distance between the coupling point and an open end of the radiating element is smaller than 0.16λ of a resonant frequency of the directional antenna.
