ABSTRACT:
According to the present invention, a small-sized electromagnetic wave measuring apparatus is provided which can simply measure an electromagnetic wave radiated from an antenna to be measured. The electromagnetic wave includes: a holder for holding the antenna to be measured; a plurality of probe antennas, provided on a circle having a center substantially at the holder, for detecting the electromagnetic wave radiated from the antenna to be measured; and a rotating unit for rotating the holder around a direction substantially perpendicular to a normal of the circle as a rotation axis.
