基于拓扑学的概念，设计了一种新型的莫比乌斯带单极天线（MBMA），与普通印刷圆圆盘单极天线（PCDMA）相比，可以实现雷达横截面（RCS）的降低。莫比乌斯带的特性实现了天线RCS的降低。模拟和实验验证了该天线的超宽带相关特性，包括回波损耗和辐射方向图。莫比乌斯带天线和参考天线都是超宽带天线，研究并比较了它们在不同负载下的RCS性能。结果表明，该天线在整个频段内的RCS都低于参考天线，同时保持了良好的辐射性能，说明MBMA是有RCS控制要求或没有RCS控制要求的天线的理想选择。
A novel mobius-band monopole antenna (MBMA) using several metallic via holes, which is based on the concept of topology, is designed to realize radar cross section (RCS) reduction compared to a common printed circular-disc monopole antenna (PCDMA). The characteristic of mobius-band realizes antenna RCS reduction. UWB-related characteristics of the proposed antenna including the return loss and radiation patterns are simulated and experimentally verified. Mobius-band antenna and the reference antenna are both UWB antennas whose RCS performances under different loads are studied and compared. The results show that the proposed antenna has lower RCS than the reference antenna in the whole frequency band while maintaining good radiation performances, which illuminates that MBMA is a good candidate for antennas with or without a requirement of RCS control.
