Abstract
A direction finding antenna includes a substrate, a reflecting ring, and a plurality of radiating elements, wherein the substrate has a surface. The reflecting ring is disposed on the surface of the substrate and is formed by connecting a plurality of side wires and is a closed polygon. Each of the side wires forms a reflector. The radiating elements are disposed on the surface of the substrate and are respectively located on an outside of the side wires, and each of the radiating elements corresponds to one of the side wires. Each of the side wires and each of the corresponding radiating elements form an antenna structure, and the antenna structures face different directions, thereby providing the needed accuracy of direction finding in different directions.
