摘要

本文研究了带半椭圆型频率选择面(FSS-shield)的矩形波导天线阵的HFSS模型的特性。结果表明，与平面无限FSS相比，屏蔽层的透明区域频率下降。在这个区域，屏蔽层会稍微改变天线阵列辐射方向图的主瓣的形状。在这个区域之外，屏蔽减少了来自天线的反向镜面散射，但增加了双基地散射。

Radiation and scattering characteristics of antenna array covered frequency selective shield

In this paper we investigated characteristics of the HFSS model of antenna array of rectangular waveguides with frequency-selective surfaces (FSS-shield) of semielliptical shape with expansion of operating band. It is shown that the region of transparency of the shield displaces down in frequency in comparison with plane the infinite FSS. In this region the shield slightly changes the form of the main lobe of radiation pattern of an antenna array. Out of this region the shield reduces backward specular scattering from the antenna, but increases bistatic scattering.
