摘要

该通信提出了一种可实现宽带雷达-红外多光谱隐身的小型天线。该天线采用双层结构：顶层是由周期性排列的方形金属贴片组成的红外屏蔽层（IRSL），底层是由极化转换超表面（PCM）元素组成的棋盘状雷达散射层（RSL）。贴片天线位于RSL的中心区域。在中心工作频率为5ghz时，天线的整体尺寸为$2\lambda _{0} \乘以$2\lambda _{0} \乘以$ 0.09\lambda _{0}$。实测结果表明，该天线工作在4.75 ~ 5.36 GHz频段内，在5.1 GHz附近的最大增益为8.6 dB。电磁波沿x、y极化方向垂直入射时，在4.44 ~ 12.76 GHz频率范围内RCS降低幅度超过8 dB(94.5%)，在4.45 ~ 12.62 GHz频率范围内RCS降低幅度超过10 dB（85.5%）。此外，PA的平均红外发射率为0.21。实验结果表明，天线能有效地控制辐射热，使热像仪下观测到的视在温度显著降低。

A Compact, Broadband, Radar-Infrared Multispectral Stealth Antenna Based on Dual-Functional Polarization Conversion Metasurface

This communication presents a compact antenna which can realize broadband radar-infrared multispectral stealth. The antenna consists of a dual-layer structure: the top layer is an infrared shielding layer (IRSL) made up of periodically arranged square metal patches, while the bottom layer is a radar scattering layer (RSL) comprises a checkerboard pattern of polarization conversion metasurface (PCM) elements. The patch antenna is located in the central area of the RSL. At the central working frequency of 5 GHz, the overall dimensions of the antenna are

$2\lambda _{0} \times 2\lambda _{0} \times 0.09\lambda _{0}$

. Measured results show that the proposed antenna (PA) operates within the 4.75–5.36 GHz band, achieving a maximum gain of 8.6 dB near 5.1 GHz. When the electromagnetic wave is vertically incident along the x and y polarization directions, the radar cross section (RCS) reduction exceeds 8 dB within the 4.44–12.76 GHz frequency range (94.5%) and 10 dB within the 4.45–12.62 GHz frequency range (85.5%). Moreover, the PA’s average infrared emissivity is 0.21. Experimental results show that antenna can control radiative thermal effectively, leading to a significant decrease in the apparent temperature observed under a thermal imager.
