摘要

研制了一种具有低旁瓣和变波束倾斜特性的基站天线。在低副瓣特性合成中，提出了一种具有多副瓣波纹的新型设计物镜图样。然后提出了一种简单的阵列群馈电方案，以实现规定的波束倾斜角度，保持低旁瓣特性。得到了最优群数。

Low sidelobe and tilted beam base-station antennas for smaller-cell systems

A base-station antenna, which features both low sidelobe and variable beam tilt characteristics, is developed. A novel design objective pattern with many sidelobe ripples is proposed in synthesizing low sidelobe characteristics. A simple array group feed scheme is then proposed to realize a prescribed beam tilt angle, maintaining low sidelobe characteristics. The optimum group number is derived.<>
