| 1. An array antenna apparatus comprising:
a first antenna element positioned at a center of an outermost concentric circle having a radius that is decided according
to a beam width of a beam to be transmitted; and
a plurality of antenna element sets respectively arranged on circumferences of a plurality of concentric circles arranged
at a predetermined interval in an inside of the outermost concentric circle,
wherein each of the antenna element sets consists of an odd number of second antenna elements, and
wherein an antenna element exists on a straight line corresponding to the radius.
