Review of Various Designs of Periodic Structures for Frequency Selective Surfaces

چکیده
With the growing recent trends in communication, different types of antennas for various frequency ranges are being developed. Other than the operating frequency; antenna gain, return loss, VSWR and bandwidth are some of the parameters that are to be looked upon for the practicality of a particular antenna design. This review paper targets an antenna design that uses a frequency selective surface (FSS) to modify the various antenna parameters. An FSS is an array of periodic structures of either metallic patches on a substrate or a conducting screen perforated with apertures, which exhibits filter characteristics for the EM wave incident upon it. In this paper, a number of frequency selective surfaces with different shapes and sizes of periodic structures have been reviewed.

Complementary Periodic Structures for Miniaturization of Planar Antennas
In this paper various layered planar periodic structures which provide miniaturization of planar antennas are proposed and discussed. The proposed designs are based on two concepts, reactive impedance surfaces and complementary periodic structures. In the proposed structures, complementary periodic rings and slots are patterned on the intermediate boundaries of the dielectric layers. A patch an...
متن کاملIn-plane Band Gaps in a Periodic Plate with Piezoelectric Patches
A plate periodically bonded with piezoelectric patches on its surfaces is considered. The differential quadrature element method is used to solve the wave motion equation for the two-dimensional periodic structure. The method is very simple and easy to implement. Based on the method, band structures for in-plane wave propagating in the periodic piezoelectric plate are studied, from which the fr...
متن کاملDesign of Novel Reconfigurable Frequency Selective Surfaces with Two Control Tech- Niques
Novel reconfigurable frequency selective surfaces (RFSS) are designed using a finite-difference time-domain with periodic boundary condition (FDTD/PBC) algorithm. The FSS are reconfigured using two techniques: the first technique providing a wide frequency tuning range is based on using diodes to change the current distribution over the FSS surface, and the second technique exhibiting a finer f...
متن کاملAn Intelligent Non-Trial-and-Error Design Method for Double Screen Frequency Selective Surfaces
An intelligent design method of double screen frequency selective surfaces (FSSs) is addressed in this paper. The employed unit cell is composed of two metallic screens, which are printed on both sides of a substrate. The presented non-trial-and-error approach is investigated based on the separate design of each screen. With the help of some physical intuition and an equivalent circuit model, i...
متن کاملNew UWB Shielding with Frequency Selective Surfaces
In this paper a Frequency Selective Surface (FSS) as a UWB electromagnetic shield is introduced. The proposed FSS comprises a quasi-J.C-Jerusalem Cross- and a copper ring, which are located at both sides of a FR4 substrate and can represent a S.E -Shielding Effectiveness- better than 20dB in 90% bandwidth of Ultra Wide Band frequency. This structure is compact and thin. Each cell comprises J.C ...
