The extent of a rectangular ground plane for measuring electromagnetic interference with a pair of tuned half-wave dipole antennas is discussed. The effects of the four edges of the ground plane were considered by GTD, and the current distribution on dipole antennas was analyzed by using the method of moment. The calculations of the normalized site attenuation(NSA) were done for the case that measuring distance was 3m or 10m, and for both borizontal and vertical polarizations. These results are compared with NSA calculated for electrically small dipoles in place of half-wave dipoles.
