PROBLEM TO BE SOLVED: To provide an antenna device, a transceiver device, a transmission/reception system and a transmission/reception method, capable of recognizing the positional deviation of a transmission/reception antenna to bring the antenna close to an ideal opposite state.SOLUTION: The antenna device includes a first array antenna, constituted by a plurality of first antenna elements, to perform short-range radio communication with a mobile terminal including a second array antenna constituted by a plurality of second antenna elements corresponding to the plurality of first antenna elements. The antenna device further includes: a coarse adjustment unit for performing coarse adjustment of a relative position between the first array antenna and the second array antenna; and a fine adjustment unit for performing fine adjustment of the position of the first array antenna, on the basis of the RSSI of each pilot signal, transmitted from each of the plurality of second antenna elements in the second array antenna and received by the plurality of first antenna elements of the first array antenna, after the coarse adjustment. |
