Calibration and use of antennas, focusing on EMC applications.

This document addresses the calibration of antennas in the frequency range 30 Hz to 40 GHz. Guidance is given on the assessment of uncertainties in their use for radiated emission measurements according to EMC standards. The National Physical Laboratory operates calibration services for the measurement of antennas factors of monopole, loop, dipole, biconical, log-periodic and horn antennas which are used for emission testing on open area test sites and in fully anechoic chambers. Most of the calibration methods and the advise given applies to the use of antennas in other applications.
