Abstract
A parasitic array antenna and a beamforming method for such a parasitic array antenna are disclosed. The parasitic array antenna may include a single driven element at the center of a ground plane. The driven element may be surrounded by multiple parasitic elements. RF loading may be selectively applied to each parasitic element. When symmetric loading is applied to the parasitic elements, the parasitic array antenna may function as an omnidirectional antenna. When asymmetric loading is applied to the parasitic elements, a null and a directional beam may be formed for the parasitic array antenna, therefore providing beamforming capabilities to the parasitic array antenna.
