摘要

提出了一种基于可重构部分反射面(PRS)的宽带探测馈电波束导向天线。PRS与馈电天线形成法布里-珀罗谐振腔，使波束的辐射特性得到改善。该吸波结构可以散射向外传播的电磁波，从而减小天线的雷达截面。PRS单元的相位随负载二极管的电参数变化而变化，从而实现波束控制。当谐振频率为5.5 GHz时，波束倾斜角可达到0°、±8°和±16°，峰值增益可达11.1 dBi。

Reconfigurable Partially Reflective Surface based Beam-Steering Antenna with RCS Reduction

In this paper, a beam-steering (BS) antenna based on reconfigurable partially reflective surface (PRS) with a wideband probe feed is proposed. The PRS and feed antenna form a Fabry-Perot resonance cavity, which leads to the improvement in the radiation characteristics of the beam. The abosrbing structure can scatter electromanetic waves propagating externally, and thus reduce the antenna radar cross section. The phase of PRS unit changes with electrical parameters of loaded diodes, thus achieving beam-steering. The beam tilting angle can be deflected to 0°, ±8° and ±16° in elevation when resonating at 5.5 GHz, and the peak gain up to 11.1 dBi is noted.
