- Abstract
- When the phase center of an antenna and the rotation center are not perfectly aligned, phase drift occurs in the antenna pattern measurement. This issue becomes more severe at higher frequencies. This paper presents a method for estimating and compensating for phase center offset, even when the phase center offset is unknown. Additionally, experimental results of horn antenna patterns measured at 159 GHz using the proposed method are provided.
