Abstract
An antenna array includes a common carrier and four microstrip antennas disposed on the common carrier. The common carrier has a first direction and a second direction that is perpendicular to the first direction. The four microstrip antennas are arranged in a matrix along the first direction and the second direction. Each of the four microstrip antennas includes an antenna structure and a power divider. The antenna structure includes a circular body and two circular feeding points that are surrounded by the circular body and do not connect to the circular body. The power divider can feed signals to the two circular feeding points. Any two adjacent ones of the antenna structures along the second direction have a two-fold rotational symmetry relationship, and any two adjacent ones of the power dividers along the first direction or the second direction have a mirror-symmetrical relationship.
