Abstract
In order to meet the needs of millimeter(mm)-wave communication for reducing interference to satellite communications within the same frequency band, this paper presents a new synthesis method based on the iterative Fourier transform (IFT) algorithm to obtain a pattern with low average sidelobe level (ASLL) within a specific angle range. And the beamwidth control (BWC) method is also added in the procedure to control the pattern beamwidth. The optimization results show that the proposed method can obtain an ASLLS of -43.31 dB within the required angular range and basically no increase in beamwidth for the 288-element planar array by optimizing the phase and amplitude of the element excitations.
