4th-EAW-ICASEAT2024 - Review of Frequency Selective Surface (FSS) Filters: Advancements in Fabrication Materials and Techniques

Abstract

This paper provides a general overview of fabrication materials and techniques for frequency selective structures (FSS) filter, from conventional printed circuit board (PCB)-based designs to ink, textile and metamaterial. Various fabrication techniques and solutions documented in numerous journal and conference publications are presented, and several examples of each approach are given. Theoretical aspects of FSS are explained to provide a basic understanding of the principles of the filter. In addition, key physical parameters with significant effects on FSS performance are identified, including the electrical conductivity of the conducting FSS element and the relative dielectric constant, as well as equivalent circuit models. The article concludes with a comparative analysis of the materials and techniques, highlighting the advantages and limitations of each method, while also addressing future challenges associated with their implementation.
