Phase Noise Suppression For Antenna Near-Field Measurement At Submillimeter Wave Band

This paper proposes an iterative method to mitigate the phase noise for assessing the radiated power density of antenna from the near-field measurement. This method iteratively calculates the field propagates forward and backward between the measurement plane and the antenna aperture. In this paper, a circular horn antenna is adopted as the antenna under test and added white Gaussian noise is adopted as the random phase noise. The numerical analysis of the obtained result demonstrates that the proposed method can effectively mitigate the phase noise.
