Abstract:
An array antenna forming unit (22) combines at least two transmission/reception devices (40) to thereby sequentially form one array antenna. Every time an array antenna is formed, an array antenna transmission/reception control unit (25) sends a radio signal having a predetermined directivity pattern from the array antenna to each of some or all of other antenna elements (42) not forming the array antenna. An array antenna communication performance measurement unit (26) measures a reception level in each of some or all of the antenna elements (42) with respect to a transmission from each array antenna, and calculates respective array antenna communication performance values, based on the measured reception levels. An array antenna determining unit (23) determines a combination of at least two transmission/reception devices (40) forming an array antenna having a predetermined performance condition, based on the array antenna communication performance values.
