摘要

In this letter, a dual-passband frequency selective surface (FSS) at Wi-Fi operation bands is presented. The proposed structure is implemented by two-dimensional periodic array of double square slots on single dielectric layer, which can be used to isolate the intensive care rooms of hospitals from insignificant signals, but supports Wi-Fi features, enabling doctors to acquire the patients' health condition at any time. The design procedure is based on the equivalent circuit method (ECM) combined with the genetic algorithm (GA) curve-fitting, which aims at providing the initial dimension parameters of FSS. Ultimately, the calculated results from the ECM are compared with the numerical results of the HFSS optimization, and the measured frequency response of the fabricated FSS covers all the Wi-Fi frequency bands, which verify the reliability of this design.
