Automated design of 5 GHZ Wi-Fi FSS filter

Abstract

This article presents a technique for analysis and automated design of frequency selective surfaces. The approach allows to automate the whole process of the filter design and frees the users from the detailed knowledge of the filter design theory. Whole process of automation is implemented in Matlab. An optimisation of a band-stop filter for Wi-Fi communication on 5 GHz serves as a practical example. Therefore the goal is to design a band-stop filter which ideally does not transmit mentioned band of frequencies. The geometry of double-layer Jerusalem-cross serves as a structure to be optimized.
