Abstract: The present invention relates to a communication device and an electronic device having the same. A communication device according to an embodiment of the present invention comprises: first to third antennas arranged to be spaced different distances from each other; first to third transceiving units; and a processor for controlling the first to third transceiving units, wherein the processor calculates a first phase difference on the basis of a difference between a first reception signal received by the first antenna and a second reception signal received by the second antenna, calculates a second phase difference on the basis of a difference between the first reception signal received by the first antenna and a third reception signal received by the third antenna, and calculates location information of an external communication device on the basis of the first phase difference and the second phase difference. Therefore, the present invention can accurately calculate the location information of the external communication device.
