Complementary Frequency Selective Surface (CFSS): Concept and Design
Frequency Selective Surface, FSS, Complementary Frequency Selective Surfaces, CFSS
Wireless communication is an integral part of modern society, having fundamental role in the process of globalization and technological development. Therefore, several researches are carried out in order to achieve constant optimization in this area. Frequency Selective Surfaces (FSS) have been approached for decades because of its telecommunications functionalities. Due to evolution of technology, new demands arise every day with specific answers for each application, thus, the FSSs need to be modeled to meet the most diverse requirements. In this context, the present work aims to show a specific model of FSS. The Complementary Frequency Selective Surfaces (CFSS) have very interesting characteristics for modern communication systems, such as multi-band frequency behavior, high selectivity in transmission bands and great angular stability, being useful in a wide range of applications, such as aircrafts, radomes and satellite communication. As part of this work, new unit-cell geometries for CFSS will be proposed and analyzed, comparing the simulated results with those of constructed prototypes and indicating possible applications.
