【摘要】 本文构造了一种适用于平面宽角扫描相控阵的特殊子阵。针对子阵的幅度和相位分布,设计了相应的馈电结构。以该子阵作为辐射单元,组建了五单元一维低剖面宽角扫描相控阵天线,其剖面高度仅为21毫米(0.14倍波长)。仿真结果表明在±70°的扫描角范围之内,主波束的增益波动值小于3dB,远优于传统设计。更多还原

【Abstract】 A design of the special sub-array for the planar wide-angle scanning phased array is proposed in this paper.A corresponding feeding structure is designed to realize the amplitude and phase distribution of the sub-array.A low-profile scanning linear array antenna on one dimension is built with five proposed sub-arrays, and the profile height is only 21 mm(0.14-wavelength).The simulated results show that the main beam can scan from-70° to +70° with a gain fluctuation less than 3 dB, which is better than the traditional designs.更多还原
