Abstract
A beam forming device includes a plurality of control circuits and a plurality of antenna elements. Each of the plurality of control circuits controls at least either phases or amplitudes of a plurality of input signals to generate a transmission signal. Each of the plurality of antenna elements outputs the transmission signal generated by a corresponding control circuit. A frequency range of the transmission signal generated by each of the control circuits is higher than frequency ranges of the input signals.
