IEEE/ANSI C63.5-2017

This standard provides methods for determining antenna factors (AFs) and associated parameters of antennas used to perform radiated emission measurements in electromagnetic interference (EMI) control from 9 kHz to 40 GHz. Antennas covered by this standard are linearly polarized antennas, such as loops, rods (monopoles), tuned dipoles, biconical dipoles, log-periodic dipole arrays, hybrids (i.e., combination broadband dipole and log-periodic dipole array antennas), broadband horns, etc., that are used in measurements defined by various ASC C63(R) emission measurements standards (e.g., ANSI C63.4 and ANSI C63.10).4 The associated compliance measurement requirements are provided within other ASC C63(R) standards. The methods used for antenna calibration measurements include the standard site method (SSM), the reference antenna method (RAM), the equivalent capacitance substitution method (ECSM), the standard transmit loop method (STLM), the standard antenna method (SAM), and the standard field method (SFM). In 4.1, the latter three methods are included in this document by reference.



Revision Standard - Active. Methods for determining antenna factors of antennas used for radiated emission measurements in electromagnetic interference (EMI) control from 9 kHz to 40 GHz are provided. Antennas included are linearly polarized antennas such as loops, rods (monopoles), tuned dipoles, biconical dipoles, log-periodic dipole arrays, biconical and log-periodic dipole array hybrids, broadband horns, etc., that are used in measurements prescribed by ANSI C63.4 and ANSI C63.10. The antenna calibration methods include standard site method (i.e., three-antenna method), reference antenna method, equivalent capacitance substitution method, standard transmit loop method, standard antenna method, and standard field method.
