本文介绍了一种用于频率选择表面（FSS）的新元件，该元件在GSM900和GSM1800两个移动通信频率范围内具有双带停止行为。制造简单、性能对入射角和偏振方向的依赖性小是发展的关键因素。FSS被实现为具有确定介电特性的墙壁的墙纸，而第二种变体可以用于任意基板。GSM下行频带的衰减为20dB，同时在广播和WLAN频率上提供最大的透明度。
This paper describes a new element for Frequency Selective Surfaces (FSS), with dual-band stop behaviour in the two mobile communication frequency ranges GSM900 and GSM1800. Easy manufacturing as well as low performance dependency on incidence angle and direction of polarization were key factors for the development. The FSS was realized as wallpaper for walls with defined dielectric characteristics, while a second variant can be used on arbitrary substrates. An attenuation of 20dB was desired for the GSM downlink bands, providing maximum transparency at broadcast and WLAN frequencies at the same time.
