چکیده

This paper deals with the theoretical investigation on a reduced sized Frequency Selective Surface (FSS). The FSS is designed by cutting a unique shaped slot into square patch. It has been shown, how the variation of the dimension of the slot and periodicity results in shifting of resonant frequency . Compared to conventional square patch FSS the designed FSS can provide reduction in resonant frequency resulting in size reduction up to 91.32% with the bandwidth of 39.54% corresponding to resonant frequency of 3.54GHz. Theoretical investigations have been done by Ansoft Designer® software. KeywordsFrequency Selective Surface, Multi frequency, Size Reduction, slot.

Equivalent Circuit Model for Square Ring Slot Frequency Selective Surface

An equivalent circuit model for predicting the frequency response of a square ring slot frequency selective surface (SRS-FSS) for normal incidence is described. The proposed FSS consists of an array of square patches centered within a wire grid. The presented circuit model is formed by the impedance of the wire grid that is parallel with the impedance of the patch array, also the mutual couplin...

A New Implementation of Frequency Selective Surface Cloak for Cylindrical Structures

The main purpose of this paper is to design, implement and measure a new sample of mantle cloak. A new method called mantle cloak is introduced by cloaking an object by a single, conformal meta-surface which can drastically suppress the scattering of the desired object. In this paper, a grid lattice is placed around a dielectric object as the cloaking structure. Previously, this FSS has been ut...

Design of Novel Shaped Compact Frequency Selective Surface With Dualband Applications

The aim of this paper is to study a Novel shaped Compact Frequency Selective Surface in wireless dualband applications as a band reject filter. Two resonating frequencies are obtained at 3.2 GHz and 10.45 GHz in this proposed FSS which cover S band and X band respectively. The FSS is designed by cutting slits and slots in the 22mm x 22mm squareshaped patch keeping same periodicity (24mm x 24mm)...

Design and Analysis of New Compact UWB Frequency Selective Surface and Its Equivalent Circuit

A compact, low profile, dual polarized, ultra wideband, frequency selective surface is proposed. It is designed by using two similar metallic array structures separated by dielectric material FR4. The simulated reflection bandwidth (with transmission < −20 dB) for TE incident wave is 8 GHz from 2.87GHz to 10.87 GHz corresponds to 116%. The unit cell dimension and periodicity are of the order of...
