“…In [13], the authors introduced the word convoluted as a general term to describe geometries of unit cells in FSS arrays where complex conductor or slot structures twist, turn and in some cases interweave. It is generally known that convoluted elements produce narrow-bands and can be used at low frequencies due to their greater electrical length [14].…”

-In this paper, we use a novel convoluted geometry to design a dual-band FSS with angular stability and independent polarization operation. The geometry allows the design of a dualband FSS to block ISM and UNII radio bands. We performed a parametric study with the commercial software ANSYS HFSS. A prototype of our proposed FSS design was built and its transmission characteristics were measured and compared with simulated results. We observed good agreement between numerical and experimental results. The proposed FSS realized a dual-band response at the required bands and it had angular stability and polarization independence.

“…The advantage of the single-layer FSSs having the dual-resonant elements is that they are light in weight and compact in volume, compared with the multilayered FSSs. The structures proposed so far are an array of two different double square loops (Wu, 1994 andChuprin, 2000), length dipoles (Hill and Munk, 1996), concentric rings Huang, 1994), and so on.…”

In this paper we will give a new way to designing spatial filters (frequency selective surfaces) being widely used in several microwave and optical systems. In this paper we will analyze transmission and reflection of electromagnetic waves from complex thick/thin metallic frequency selective surface (FSS).In this work, we have designed the spatial filter (FSS) to be used in microwave/satellite communication. We have tried to overcome the limitations in form of accuracy and computational effort. Using CST software, the results for full wave analysis method are being evaluated.

“…Recently, multiband operations with a single-layer configuration have been attempted by developing resonant elements with multiple resonant frequencies [1][2][3]. We have also optimized the resonant element shape by using a combination of a GA (genetic algorithm) and a geometry-refinement technique, so that broadband reflection characteristics with two resonant frequencies are realized [4,5].…”

SUMMARYThis paper presents an analysis of the characteristics of the frequency selective surface (FSS) by means of equivalent circuit models. In order to determine the circuit element parameters of the FSS with resonant elements of arbitrary shape, the eigenvalue problem of the matrix equation is solved and the Q curve of each resonance is derived from the frequency dependence of the reactance obtained from the characteristic current distributions at resonance. By equating this Q curve with that for the equivalent circuit, the circuit parameters are derived. As an example of analysis by the present method, the circuit element parameters of patch-type resonant elements designed by us using the genetic algorithm (GA) are derived. The characteristics of the dielectric-loaded FSS for the C/Ka band are analyzed by means of the equivalent circuit. The usefulness of the proposed method is verified by comparison of the frequency characteristics obtained by the method of moments and by the equivalent circuit.
