Abstract
A dual circularly polarized antenna structure includes a substrate, an M number of antenna arrays, and a feed module. Each of the antenna arrays includes two first antennas and two second antennas. Each of the first antennas and the second antennas includes two sub-antennas and two microstrip lines electrically coupled to the two sub-antennas. The two sub-antennas of the first antenna overlap through translation. The two sub-antennas of the second antenna overlap through translation. A center point is defined between the first antennas and the second antennas. One of the sub-antennas of each of the first antennas and one of the sub-antennas of each of the second antennas are adjacent to the center point, and have a 4-fold rotational symmetry relative to the center point. The feed module is electrically coupled to each of the antenna arrays for generating a first circular polarization and a second circular polarization.
