摘要

提出了一种具有广角扫描能力的宽带相控阵天线。天线元件利用一个i形槽来耦合来自馈电的能量，在位于其上方的两个不同尺寸的SIW腔内激发两种不同的模式。馈电点的阻抗匹配网络用于实现宽带辐射性能。同时，采用顶载偶极子增强了h面扫描特性。所得到的阵列实现了40%的带宽，同时在h平面保持了±60°的有效扫描。

Wideband Wide-Scanning Phased Array Based on Connected SIW Cavities and Slit Antenna

This paper presents a novel broadband phased array antenna with wide-angle scanning capability. The antenna elements utilize an I-shaped slot to couple energy from the feed, exciting two distinct modes within two differently sized SIW cavities positioned above it. An impedance matching network at the feed point is used to enable broadband radiation performance. Meanwhile, top-loaded dipoles are incorporated to enhance the H-plane scanning characteristics. The resulting array achieves a 40% bandwidth while maintaining effective scanning up to ± 60° in the H-plane.
