Abstract
A dual circularly polarized antenna array includes an insulating substrate, an M number of feed modules, and an M number of antenna groups. The insulating substrate includes an M number of preset points. The M antenna groups are respectively disposed on the M preset points, and each antenna group includes four antennas. Any two opposite ones of the four antennas jointly have a 180-degree rotational symmetry relative to a corresponding one of the M preset points. Each antenna includes a conductive sheet, and a first feed point and a second feed point that are electrically coupled to one of the M feed modules. The first feed points of the four antennas can jointly generate a left-hand circular polarization through one of the M feed modules, and the second feed points of the four antennas can jointly generate a right-hand circular polarization through one of the M feed modules.
