Abstract

A low-profile ultra-wideband (UWB) band-stop frequency selective surface (FSS) is designed for S-, C-, X- and Ku-bands communication applications. The FSS is constructed by using square and circular loop elements printed on the top and bottom sides of the RO3210 substrate. The FSS has been designed to reduce the electromagnetic interference (EMI) as well as to mitigate the harmful effects of electromagnetic radiation on the human body caused by different radio devices. The dimension and size of the UWB FSS have been reduced to 0.12 λ × 0.12 λ and 90%, respectively, as compared to the reported literature. The other advantages of the proposed FSS are that it is low profile, it has a simplified geometry and it ensures better angular and polarization stability of up to 85°. The –10 and –20 dB bandwidths of the proposed FSS are 146% (2.0–13.0 GHz) and 80% (4.87–11.42 GHz), respectively. Theoretical results have been obtained using ANSYS HFSS and verified through measured results.
