A New Method for Calibrating the Beam of Phased Array Antenna
SUN Yayun
Abstract：Due to the mutual coupling effect between phased array elements,the actual antenna and the ideal point source ar?ray pattern will be very different. The mutual coupling effect will make the actual direction of the beam deviate from the ideal Angle, cause energy divergence and reduce the gain of the phased array antenna. In this paper,a new calibration is proposed. By establish?ing mutual coupling matrix,the actual weight approximates the ideal weight,so as to achieve the purpose of beam pointing calibra?tion. Compared with the traditional narrow-band calibration method,this method has stronger band adaptability. It is simple and easy to operate,and is more suitable for large broadband array.
