Design of Locally Deformed Flexible Frequency Selective Surfaces
2023 International Symposium on Signals, Circuits and Systems (ISSCS)（2023）
Abstract
A one-layer frequency selective surface (FSS) is proposed for filtering applications. The initial structure consists of one square ring on one side of the supporting dielectric layer. By performing cylindrical bending on the initial structure, the stopband can be shifted, or multiple stopbands can be obtained. Parametric analyses of the frequency response as a function of substrate thickness and structure width are reported, demonstrating the flexibility of the design by allowing for the potential of modifying the stopbands. The analysis has been carried out by full-wave electromagnetic simulation in the sub-10 GHz frequency range.
