Antenna elements are provided along a linear line at regular intervals to
be parallel to each other. The antenna elements receive signals transmitted from
a communicating partner and output the signals to a receiving beam former. In the
receiving beam former, phase shifters phase-shift the received signals input from
the antenna elements of an even element number by . A combiner adds the
received signals that are phase-shifted by in phase shifters and the signals
input from the antenna elements of an odd number to form a received beam. With
this configuration, it is possible to realize an array antenna apparatus of a small
and simple configuration that reduces the radiation of radio waves to the human
body and to other equipment and that is influenced little by the human body and
by other equipment.
