摘要

本文介绍了一种符合圆柱体的集成辐射和散射性能阵列。在不加载任何其他结构的情况下，可实现宽带 RCS 降低并保持辐射性能。设计了两个具有相似辐射性能和不同反射相位的不同天线单元，组成一个 6 × 6 的共形阵列。为验证仿真结果，制作并测量了 6 × 6 单元集成共形阵列的原型。实验结果表明，在 8.2-11.3 GHz 范围内，拟议的共形阵列在 ±40° 以上具有更好的扫描性能。此外，在阵列天线的工作频段内，拟议阵列的单静态 RCS 降低超过 5 dB，最大降低值为 24.2 dB。测量结果与模拟结果十分吻合。

An AMC-based low-RCS conformal phased array design

In this article, an integrated radiation and scattering performance array conformed with the cylinder is presented. Wideband RCS reduction can be achieved and the radiating performance is maintained without loading any other structures. Two different antenna units with similar radiation performances and different reflection phases are designed to form a 6 × 6 conformal array. To verify the simulation results, a prototype of a 6 × 6 units integrated conformal array was fabricated and measured. The experimental results show that the proposed conformal array has better scanning performance above ±40° in the range of 8.2–11.3 GHz. In addition, the monostatic RCS reduction of the proposed array is more than 5 dB covering the working band of the array antenna with a maximum reduction value of 24.2 dB. The measured results agree well with the simulation results.

期刊介绍： Frequenz is one of the leading scientific and technological journals covering all aspects of RF-, Microwave-, and THz-Engineering. It is a peer-reviewed, bi-monthly published journal. Frequenz was first published in 1947 with a circulation of 7000 copies, focusing on telecommunications. Today, the major objective of Frequenz is to highlight current research activities and development efforts in RF-, Microwave-, and THz-Engineering throughout a wide frequency spectrum ranging from radio via microwave up to THz frequencies. RF-, Microwave-, and THz-Engineering is a very active area of Research & Development as well as of Applications in a wide variety of fields. It has been the key to enabling technologies responsible for phenomenal growth of satellite broadcasting, wireless communications, satellite and terrestrial mobile communications and navigation, high-speed THz communication systems. It will open up new technologies in communications, radar, remote sensing and imaging, in identification and localization as well as in sensors, e.g. for wireless industrial process and environmental monitoring as well as for biomedical sensing.
