The accuracy of H-field generation is consider in this chapter. In these considerations, only “internal” factors will be taken into account, i.e., location of a transmitting and a receiving antenna, excitation measurement error, electrical sizes of the loop antennas, and others. Because of the specificity of the standard, it is possible to neglect here any “external” factors limiting accuracy of the standard, such as the influence of ground conductivity, the presence of other conducting objects in the neighborhood of the standard, multipath propagation, or interference caused by external EMF. This simplification is acceptable because of the fact that the antennas are much smaller compared to the wavelength and, as a result, are much less sensitive to the factors mentioned. For the same reason, the H-field standards may work in a less rigorously controlled environment, with no screened or anechoic chambers.
