Design and impedance modeling for dual band and multiple band frequency selective surface (FSS)

This paper presents a dual band and multiple band frequency selective surface (FSS) on energy saving glass (ESG). In this paper, there are two designs that have been presented, namely Design A which is a combination of double strip in vertical and horizontal position and Design B is a combination of double strip in vertical and horizontal position using complementary techniques. Design A and Design B are simulated using CST Microwave Studio software. The simulation process is based on the characteristics of the reflection coefficient (S11) and transmission coefficient (S21) of the FSS. The Design A resonates at two frequencies of 1.75 GHz and 3.4 GHz. The Design B resonates at three frequencies of 0.8 GHz, 1.8GHz and 3.4 GHz.
