Abstract
An electromagnetic wave shield boxaccommodates a DUThaving an antennaand a coupling antennathat is spatially coupled to the antenna, and includes a coupling antenna holding modulethat arranges a plurality of the coupling antennasannually so that an antenna surface is directed to a center of a ring, and holds the coupling antennas. The coupling antenna holding moduleholds each coupling antennain a posture in which the coupling antennais inclined at, for example, 32 degrees with respect to a horizontal surface so that the respective coupling antennasare able to radiate radio waves toward the same radiation point in upper positions, and is rotated by about 5 degrees around a center axis Cin a direction orthogonal to a circumferential direction of the ring of the coupling antenna
