Abstract:SummaryThis research work presents a miniaturized enhanced angular and polarization stability frequency selective surface (FSS) structure at 660 MHz for electromagnetic (EM) shielding of 4G LTE networks. The vias and spiral‐shaped subunit cells are combined to extend the electrical path length corresponding to the lower resonant frequency. The symmetric structure is considered to improve polarization and angular stability. Two symmetric metallic layers are etched on both sides of the FR4 substrate with thickne… Show more
