Frequency Selective Surface (FSS) has been playing vital role in applications like antenna radomes, reflectors, absorber, electromagnetic shielding and many more. Hence, this paper has been proposed the design and analysis of novel FSS unit cell. Initially, square loop shaped unit cell has been designed which provides Band Stop characteristics for the designed frequency of 7.5 GHz. Subsequently, the hexagonal loop within the square loop shaped unit cell has been inscribed which provides both Band Pass and Band Stop characteristics at 7.4 GHz and 9.9 GHz respectively. Angular stability of the proposed unit cell has been determined by analyzing the TE and TM Polarization from 0 to 40 in the interval of 10. The proposed FSS unit cell has been arranged in 2x2 array for obtaining the meta surface characteristics and the corresponding results have been presented. All the simulations have been carried out using HFSS 2019 R2.

Abstract


Frequency Selective Surface (FSS) has been playing vital role in applications like antenna radomes, reflectors, absorber, electromagnetic shielding and many more. Hence, this paper has been proposed the design and analysis of novel FSS unit cell. Initially, square loop shaped unit cell has been designed which provides Band Stop characteristics for the designed frequency of 7.5 GHz. Subsequently, the hexagonal loop within the square loop shaped unit cell has been inscribed which provides both Band Pass and Band Stop characteristics at 7.4 GHz and 9.9 GHz respectively. Angular stability of the proposed unit cell has been determined by analyzing the TE and TM Polarization from 0 to 40 in the interval of 10. The proposed FSS unit cell has been arranged in 2x2 array for obtaining the meta surface characteristics and the corresponding results have been presented. All the simulations have been carried out using HFSS 2019 R2.
