A simple synthesis technique of single- square-loop frequency selective surface

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.
