提出了一种利用频率选择表面(FSS)实现屏蔽效能的有效方法。这种FSS由印刷在单层FR-4基板两侧的交叉偶极子和环组成，具有7.5 GHz的宽阻带，可同时屏蔽X波段和Ka波段。实验结果证实了该样机在超宽带上的误码率，测量到的衰减大于20分贝。该设计紧凑，适用于提供屏蔽辐射干扰所造成的免费和其他无线电系统。
An efficient approach to achieve the shielding effectiveness (SE) by using a frequency-selective surface (FSS) is presented. This FSS, which consists of cross dipoles and rings printed on the opposite sides of a single-layer FR-4 substrate, exhibits a wide, 7.5-GHz stopband to provide simultaneous shielding in both X-and Ka-bands. Experimental results confirm SE of the prototype over an ultra-wide band with more than 20-dB measured attenuation. The design is compact and suitable to provide shielding against the radiation interference caused by license-free and other radio systems.
