Design of Square Patch-Strip Bandpass FSS Using Equivalent Circuit Model

Author

Abstract

This paper uses an analytical formulas to estimate frequency response for the Square metal patch and strip periodic cells. Analytical expressions for frequency response are verified by fullwave simulations. The analytical formulas used in design of one-order, bandpass FSS based on circuit model. This bandpass FSS is made up of periodic array of metallic patches separated by thin air-gaps backed by a wire mesh having the same periodicity. The frequency responses are obtained for different thickness and dielectric constants substrate. The simulations are carried out using ful-wave and analytical methode, and results are compared to understand limitations of proposed designing method. Principles of operation, detailed synthesis procedure, and designing guideline for this type of FSS are presented and discussed in this paper.
