摘要

本文研究了封闭天线带通FSS天线罩在降低其工作频带外的反向RCS方面的应用。设计并构造了一种覆盖FSS天线罩的平面阵列天线。为了研究电介质嵌入FSS对封闭天线方向图的影响，我们采用射线追迹技术计算天线-FSS结构的近场方向图，由此计算出传输系数和远场方向图。结果表明，在非工作频带时，FSS天线罩天线阵列的后向RCS比普通天线阵列显著降低。

The analysis and measurement of FSS radome for antenna RCS reduction

This paper investigates the application of bandpass FSS radome with an enclosed antenna to reduce its backward RCS outside of its operating band. A planar array antenna covered with FSS radome is designed and constructed. In order to study the effects of a dielectric embedded FSS on an enclosed antenna pattern, we adopt the ray tracing technique to compute the near field pattern of the antenna-FSS configuration, from which the transmission coefficient and the far field patterns can be calculated. The results show that the backward RCS of antenna array with FSS radome has dramatically reduced than the common antenna array at out of operating band.
