本文研究了平面阵列天线综合折射率和频率选择表面对其后向RCS和辐射方向图的影响。结果表明，介质层集成在天线表面时，可以优化天线的辐射方向图，而介质层与天线表面有一定距离时，对天线的辐射方向图影响不大。介质层对天线的RCS影响很小。单层FSS集成在天线表面时，使天线的辐射方向图明显变差，而当放置在天线表面上方一定距离时，对天线辐射方向图的影响很小。而单层频率选择表面可以显著优化天线的带外RCS。
This paper investigates the efiect of a planar array antenna integrated with dielec- tric and FSS to its backward RCS and radiation pattern. The results shows that dielectric layer can optimize radiation pattern of antenna when it is integrated on the surface of antenna, while rarely in∞uence radiation pattern when dielectric layer have some distance from antenna surface. And, dielectric layer in∞uences the RCS of antenna very little. One-layer FSS makes radiation pattern of antenna signiflcantly bad when it be integrated on the surface of antenna, while when it is put some distance above the surface of antenna, it's in∞uence to radiation pattern of antenna get very little. However one-layer FSS could dramatically optimize antenna's RCS at out of band.
