摘要：
There is provided a communication device including: a receiving unit that receives radio signals transmitted from another communication device using a plurality of transmitting antennas by a plurality of receiving antennas; an estimation unit that estimates a range of a position where said another communication device possibly exists based on a phase of each radio signal received by the receiving unit and antenna spacing between the transmitting antennas; and a position determination unit that determines an existing position of said another communication device within the range estimated by the estimation unit.
