Abstract
A circular polarized antenna array module and a wireless communication device, including a plurality of circular polarized transmitting antennas and circular polarized receiving antennas, a dielectric substrate, and a plurality of first group of phase shifting units and second group of phase shifting units. In each row of the circular polarized transmitting/receiving antennas, every two adjacent circular polarized transmitting/receiving antennas arranged with a distance, each of the circular polarized transmitting antennas arranged with a first feed point and a second feed point, each of the circular polarized receiving antennas arranged with a third feed point and a fourth feed point. Each row of the circular polarized transmitting antennas and each row of the circular polarized receiving antennas alternately placed to form array arranged on the dielectric substrate. The first/second group of phase shifting units adjust phases of transmitting signals/return signals of the circular polarized transmitting/receiving antennas.
