摘要： The present disclosure provides a two-dimensional antenna system. The two-dimensional antenna system includes a transmitting antenna array and a receiving antenna array. The transmitting antenna array includes one or more circularly polarized transmitting antennas having a first direction of rotation. The receiving antenna array includes two or more first circularly polarized receiving antennas having a second direction of rotation arranged in a first direction, and two or more second circularly polarized receiving antennas having the second direction of rotation arranged in a second direction. The first direction is perpendicular to the second direction, and the first direction of rotation is opposite to the second direction of rotation.
