The wide diffusion of electric and electronic equipment creates problems of electromagnetic compatibility and electromagnetic pollution, giving evidence of the importance of electromagnetic field measurements and, consequently, of the calibration of the measuring equipment. This paper describes a calibration method, applicable to small antennas operating in the frequency range from about 10 MHz to 3 GHz. By applying this method the antenna under calibration is placed in a GTEM cell, where an electromagnetic field, previously evaluated with a transfer standard, is generated. The resulting calibration uncertainty is about 1.6 dB (k = 2), not so far from the “state of the art” uncertainty.

Abstract
The wide diffusion of electric and electronic equipment creates problems of electromagnetic compatibility and electromagnetic pollution, giving evidence of the importance of electromagnetic field measurements and, consequently, of the calibration of the measuring equipment. This paper describes a calibration method, applicable to small antennas operating in the frequency range from about 10 MHz to 3 GHz. By applying this method the antenna under calibration is placed in a GTEM cell, where an electromagnetic field, previously evaluated with a transfer standard, is generated. The resulting calibration uncertainty is about 1.6 dB (k = 2), not so far from the “state of the art” uncertainty.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
