Abstract
A base station device provided with a plurality of antennas has a mode, in which all the antennas are used, and a mode, in which the plurality of antennas are divided into a plurality of groups each including two or more antennas to be used independently. An array antenna pattern is formed selectively in these modes. When the array antenna pattern is to be formed in the mode of using all the antennas, a signal of one synthesizer is applied to transmission/reception circuits of all the antennas. In the mode of using antennas divided into the plurality of groups, signals of different synthesizers are supplied to the transmission/reception circuits of the antennas.
