The invention provides a circularly polarized array antenna and a circularly polarized array antenna module. The circularly polarized array antenna may include: a dielectric material substrate; and at least one unit antenna including a plurality of radiators which are sequentially arranged on the dielectric material substrate in a turning direction such that feed portions of the plurality of radiators have a phase difference. The plurality of radiators may be arranged in an inclined direction with respect to a first direction and a second direction crossing each other. Radiators of the plurality of radiators that are adjacent to each other in the first direction or the second direction may be spaced apart by a gap that is at least a width of the radiators that are adjacent to each other in the first direction or the second direction. 本公开提供一种圆极化阵列天线和圆极化阵列天线模块。所述圆极化阵列天线可包括：介电材料基板；以及至少一个单元天线，包括多个辐射器，所述多个辐射器在旋向方向上顺序地布置在所述介电材料基板上，使得所述多个辐射器的馈电部具有相位差。所述多个辐射器可相对于彼此交叉的第一方向和第二方向在倾斜方向上布置。所述多个辐射器中的在所述第一方向或所述第二方向上彼此相邻的辐射器
