| Abstract: |
| A method for analyzing the equivalent circuit model of frequency selective surface(FSS) in multilayer substrates is proposed based on numerical simulation and microwave network theory. It has the virtue of intuitive physical process and small calculations. Moreover,the model can be applied to two-dimensional arbitrarily-shaped FSS. The equivalent circuit of square patch FSS is studied as an example to validate the feasibility of the proposed method,and the influence of multilayer substrates on the equivalent circuit parameters of patch FSS is investigated as well. Finally,a bilayer of band-pass FSS is designed based on filter theory and the equivalent circuit model,the calculation results show that the simulation results agree very well with the theoretical value. It provides a way to precisely synthesis the multilayer FSS. |
