Dual-polarization angle-selective surface structure with adjustable passbands and wide-angle selection characteristics
Year: 2024
Type: article
Abstract: Due to the current limitations of angle-selective surface structures that cannot simultaneously meet the ideal angular selection characteristics, adjustable passbands, and dual polarization, an angle-selective surface structure with a wide-angle selection characteristic and adjustable passbands based on a three-layer frequency-selective surface is presented. Through theoretical analysis, calculation, and simulation derivation, a three-layer cross-slotted structure was ultimately selected as the unit structure for this design. The proposed three-layer angle-selective surface structure features identical upper and lower structures, while the middle layer structure is different from both. The simulation results indicate that the proposed design displays a passband (|S 21 |>-1 dB) within the incident angle range of 0° to 23.5° at a frequency of 3 GHz for the TE and TM polarization modes, and shows a stopband (|S 21 |<-20 dB) when the incident angle is greater than 36°. Although various factors influenced the simulation results, we believe that the simulation results will provide valuable reference for researchers in the relevant field.
