A New Calibration Method for an Electric-field Probe using TEM Waveguides

Abstract

Standard gain horn antennas are used as transmitting antennas for the calibration of an electric-field probe above 1 GHz. However, it is difficult to use horn antennas at frequencies below 1 GHz because of their very large dimensions, which make them difficult to handle. Hence, a calibration method for frequencies below 1 GHz is also required. A probe calibration method using a one-port TEM waveguides is proposed in this paper.
