Investigation of impedance modeling for a unit cell of the circle loop Frequency Selective Surface at 2.4GHz

In this paper, we present a mathematical impedance modeling for a unit cell of the circle loop Frequency Selective Surface (FSS) structure. The unit cell of the circle loop FSS is designed and simulated based on industrial, scientific and medical bands (ISM) standard by using the CST Microwave Studio software. The configuration of FSS is simulated for two types; single layer and dual layer FSS. Based on physical parameters of the design structure of the FSS, real and imaginary component of the design has been modeled mathematically.
