Characterization of Artificial Magnetic Conductor, Electromagnetic Band Gap and Frequency Selective Surface

Abstract

This paper investigates the characteristics of Artificial Magnetic Conductor (AMC), Electromagnetic Band Gap (EBG) and Frequency Selective Surface (FSS) at 5.8 GHz. Reflection magnitude and phase are characterized both AMC and EBG meanwhile, the band gap is specially characterized by the EBG structure. Besides that, transmission and reflection coefficients are used to characterize the FSS structure. Three different flexible substrates are considered which are Fast Film, Arlon AD350 and Rogers RO3010. Then, angular stability is analyzed for each structure. In order to design AMC, EBG and FSS by using thin substrate, the highest dielectric constant is needed to develop a compact structure with the highest bandwidth. Later, AMC, EBG and FSS structures can be used to improve the radiation pattern apart from enhancing the realized gain of a low profile antenna such as dipole antenna.
