摘要

本文提出了一种低轮廓的宽带相控阵。该天线单元由层叠贴片天线组成，由打印的弯曲探针馈电。馈电机构补偿了传统探头产生的电感，印刷电路技术有助于集成。在天线阵中，金属柱和金属壁在天线单元周围周期性布置，为消除工作波段的扫描盲性提供了解决方案。周期无限阵列的仿真结果表明，在±60°扫描角范围内，中心单元具有超过40%的带宽(有源VSWR<2)和良好的辐射方向图。

A Broadband Low Profile Phased Array Antenna

A wideband phased array with low profile geometry is presented in this paper. The antenna element consists of the stacked patches antenna fed by the printed meandering probe. The feeding mechanism compensates the inductances caused by the conventional probe, and the printed circuit technology conduces to the integration. In the array, the metallic posts and walls are periodically arranged around the antenna cell, which provide the solution to eliminate the scan blindness in the operation band. The simulated results of the periodical infinite array show the center element has an over 40% bandwidth (active VSWR<2) within ±60° scan angle and good radiation patterns.
