Antenna factor determination with Antenna Impedance measurements

DOI

Description

In the fields of electromagnetic interference and electromagnetic compatibility, it is important to measure the strength of the electric field originating from electric devices. For this purpose, knowledge of the antenna factor of a receiving antenna is necessary. In this paper, we discuss the recently measurement methods called Antenna Impedance Method as a new calibration method able to obtain the free-space antenna factor. The experimental measurements of the antenna factor obtained with this method were compared with Standard Field Method and the data provided by the manufacturer of three antennas data (Biconical, Log-periodic and Horn antenna) founding an agreement with the norm applicable to the calibration of antenna ANSI C63.5.
