Abstract
A circularly polarized array antenna may include: a dielectric material substrate; and at least one unit antenna including a plurality of radiators arranged sequentially in a rotational direction on the dielectric material substrate such that feeders of the plurality of radiators have a phase difference. The plurality of radiators may be arranged in a diagonal direction with respect to a first direction and a second direction crossing each other. Radiators neighboring each other in the first direction or the second direction, among the plurality of radiators, may be spaced apart by a gap of at least a width of the radiators neighboring each other in the first direction or the second direction.
