摘要
设计了一种L波段双脊波导裂缝阵列天线。该天线具有好的频率响应特性,实现了低副瓣,水平垂直两个面的交叉极化得到了有效抑制。由于馈电双脊波导的截面尺寸大幅度减小,使得这项研究将有很好的应用前景。
An L-band double-ridged waveguide slot array antenna is designed,featuring good frequency response and low sidelobe,and the cross polarizations in the horizontal and vertical planes are effectively suppressed.The research can have a good application prospect due to the RCS reduction of the feed double-ridged waveguide to a large extent.
