摘要
This paper presents a novel design of frequency selective surface (FSS) with band-stop characteristics at dual frequency bands. The FSS element is a hybrid set consisting of four meander lines square loops and a criss-cross element, and can be implemented on a single-layer PCB substrate at low cost. It is found that the band-stop characteristics are valid for a relatively wide angular range of field incidence. Furthermore, structural parameters have been identified for the adjustment of flexible band separation. In this work, an equivalent circuit model is further developed to illustrate the electrical properties of band-stop as a space filter. The concept has been validated by considering a prototype at 6.3 and 8 GHz, where the simulation and measurement frequency responses are compared to exhibit the transmission characteristics of this FSS design.
