ANSI C63.5-2006
American National Standard for Calibration of Antennas Used for Radiated Emission Measurements in Electro Magnetic Interference
This standard provides methods for determining antenna factors of antennas used for radiated emission measurements of electromagnetic interference (EMI) from 9 kHz to 40 GHz. Antennas included are linearly polarized antennas, such as loops, rods (monopoles), tuned dipoles, biconical dipoles, log-periodic dipole arrays, hybrid linearly polarized arrays, broadband horns, etc., that are used in measurements governed by ANSI C63.4-2003.1 The methods include standard site, reference antenna, equivalent capacitance substitution, standard transmitting loop, standard antenna, and standard field methods. The latter three methods are incorporated by reference in 4.5.
Harmonization of this standard with international standards is achieved by providing one-measurement geometry in the 30 MHz to 1000 MHz frequency range. The word “shall” is used in this document to indicate mandatory requirements. The words “should” or “may” are used to indicate that among several possibilities one is strongly recommended but not mandatory.
