A Simple Synthesis Technique of Single-Square-Loop Frequency Selective Surface

Abstract

Abstract-In this manuscript, a simple synthesis method of single square loop frequency selective surface (SSLFSS) is discussed, which may find the suitable application in the fast analysis and fabrication of the frequency-selective surface. The presented technique is used to design SSLFSS at 3 GHz, 15 GHz, 22 GHz and 26 GHz. At every frequency of interest, the analytical result is very close to the required result. Moreover, a way to control the reflection at any frequency is discussed, which may find an application in controlling the reflection level at any frequency. However, we have proposed two simple, cheaper and lightweight structures at 3 GHz and 22 GHz for the application in various satellite communications. The proposed process has been extended to the analysis of bandpass structure and desired results have been achieved, which indicates the utility of the method of synthesis of both the bandpass and bandstop structures.

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

“…The value of the inductance L f and capacitance C f can be approximated by considering the conventional loop and given by following relations [15,18] …”

“…An Ultra Wideband (UWB) FSS can be designed using multilayer loop type FSS [12]. The analysis of loop type FSS has also been done using different approaches [13][14][15][16][17].…”

“…FSSs with angular-dependent behaviors are widely used in microwave, millimeter wave, and optic wave regimes of the spectrum, where they can act as either band-pass or band-stop filters [1,5,7,13]. Owing to several features, they are preferable since they increase the directivity, gain, and polarization purity of the received signals; in addition, bandwidth and frequency stabilization is possible by using these structures [11,12]. Due to their advantages, they are used in antenna radome design in order to prevent the interaction of electromagnetic waves and they are used in radar cross-section reduction by providing filtering [13].…”

“…Especially for application areas requiring operation safety, high performance and stability in systems filtering electromagnetic waves appear to be one of the most important problems for engineers. In the literature, several periodic arrangements are used with different geometries as a way of filtering electromagnetic waves [1][2][3][4][10][11][12][13]. Periodically arranged surfaces, which are manufactured in order to use in blocking or passing a frequency band, can be excited by two different methods.…”

“…Wireless communication is one of the examples that the theory reached a level of maturity as well as the application areas especially in the microwave branch. Radar systems, antenna design, and broadband communication are examples for those areas [1][2][3][4][5][6][7][8][9][10][11][12][13]. Due to the development in microwave technology, various forms of electromagnetic waves with different frequencies are used to communicate, which causes several problems resulting from the interference of electromagnetic waves, since those waves interact with each other and with the environment [1,2].…”
