Elimination of Unintended Reflection Waves from a Test Site for Antenna Calibration using the MUSIC Algorithm

Abstract

The antenna used for EMI measurements is calibrated at test sites, such as open area test sites or in anechoic chambers. The unintended reflection waves from the test sites cause uncertainty in the measurements. In this paper, the MUSIC algorithm was used to eliminate the unintended reflection waves from the test sites, and the antenna gain was determined by using the three-antenna method.
