Low radar cross section microstrip antenna based on left‐handed material

Zhang Jia Kai; Xu Jia Chen; Ding Jun; Guo Chen Jiang

摘要

Abstract >This article designs a hexagonal left‐handed material (LHM) and proposes a microstrip antenna with low radar cross‐section (RCS) based on this new LHM. The modified antenna RCS is significantly reduced without reducing radiation performance compared with two reference antennas. The scattering distribution shows the RCS reduction is attributable to the LHM. Antenna prototypes are fabricated and measured to verify the simulation. As a result, the modified antenna realized RCS reduction while maintaining radiation performance, with 19.5 dB maximum RCS reduction at 1.16?GHz, and the out‐of‐band RCS reduced due to the converged electromagnetic wave caused by the LHM. </abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> <div class="translation abstracttxt"> <span

>本文设计了六边形左手材料（LHM），并提出了一种基于该新LHM的低雷达横截面（RCS）的微带天线。与两个参考天线相比，改进的天线RCS显着降低而不降低辐射性能。散射分布表明RCS减少可归因于LHM。制造和测量天线原型以验证模拟。结果，改进的天线在保持辐射性能的同时实现了RCS降低，其中19.5dB的最大RCS减小为1.16≤GHz，并且由于由LHM引起的融合电磁波而减小了带外RC。</ p>
