This article introduces analytical formulas to obtain frequency response for a periodic array of hexagon metallic patches and strip cells. The validity of analytic expressions obtained from analysis is verified using full-wave simulations. The formulas are then employed for designing a first-order bandpass frequency selective surface. The proposed frequency selective surface is composed of a periodic array of metallic patches separated by thin air gaps backed by a wire mesh having the same periodicity. The array of metallic patches and the wire mesh constitute a capacitive surface and a coupled inductive surface, respectively, which together act as a resonant structure in the path of an incident plane wave. The frequency response of the proposed frequency selective surface is obtained for various angles of incidence. Moreover, principles of operation, detailed synthesis procedure, and designing guideline for this type of frequency selective surface are presented and discussed in this article.

“…For secondary or higher ordered grating lobe suppression, according to the diffraction theory, the size and periodicity of the resonant elements should be smaller than the wavelength of the incident radiation, otherwise the resonant optical properties of the FSS structure may be related to the coupling between adjacent elements, thus depending on the angle-of-incidence (AOI) of the incoming waves. Several resonant classical shapes for FSS design, for example, a circular loop [3], square loop [4,5], hexagonal [6], and fractal geometries [7,8] have been discussed based on the applications.

Azimuthally periodic wedge-shaped metal vane loaded circular ring frequency selective surface garima bharti 1 , kumud ranjan jha 2 , ghanshyam singh 1 and rajeev jyoti 3In this paper, the analysis and simulation of a novel geometrical structure of the frequency selective surface (FSS), which has been achieved through the conductive loading of the simple circular ring with wedge-shaped metal vanes has been discussed. The electrical performance and behavior of the proposed structure have been studied in Ku band (12-18 GHz) of the electromagnetic spectrum for satellite communication. We have radially optimized the proposed structure to enhance the performance, such as reflection and transmission bandwidth. We have also discussed the effect of incident electric field at 08, 108, 308, and 508 on the electrical performance of the proposed FSS. In addition to this, the effect of angular sensitivity on the proposed structure through increasing the number of conductive loaded wedge-shaped metal vanes is also explored. However, the structural parameters of the proposed FSS have been obtained through the synthesis technique. The analytical results obtained from the synthesis technique have been supported by the simulation results achieved through CST Microwave Studio as well as Ansoft high frequency structural simulator (HFSS), which are commercially available simulators based on the finite integral and finite-element technique, respectively. Furthermore, for validation of the numerical results, the Ansoft circuit simulator which is based on mixed potential integral equations (MPIE) and solved by the method-of-moment has also been used to obtain the reflection and transmission parameters through the values of inductance and capacitance, which have been achieved by the numerical analysis.

This article presents a fractal design methodology for frequency selective surfaces (FSSs) by printing a finite planar array of Vicsek fractal metallic patches on a single dielectric layer. Shapes presented by the Vicsek fractal as a function of the fractal parameters (level and scale factor) were exploited to design FSSs acting as dual‐polarized band‐stop spatial filters for incident plane waves. Transmission properties of these FSSs were analyzed and two FSS prototypes were built and measured to validate the fractal design methodology. The obtained results pointing to interesting FSS properties: a high frequency compression factor of 50.31% and stable resonance frequency at oblique incidence. © 2012 Wiley Periodicals, Inc.
