Frequency-Selective Structure With One Reflection Band And Two-sided Absorption Bands

An absorptive frequency-selective reflection structure with one reflective band and two-sided absorptive bands is presented in this paper. The structure, equivalent circuit model and working principle are investigated. Simulation results show that a reflective band at 5.86-6.83 GHz and two absorptive bands at 3.21-4.92 GHz and 7.41-10.99 GHz are obtained.
