Automated design of frequency selective surfaces with the application to Wi-Fi band-stop filter
Original language description
This article presents a technique for analysis and automated design of frequency selective surfaces. In this work the method of moments is used to analyse a planar periodic structure. The approach allows to automate the whole process of the filter designand frees the users from the detailed knowledge of the filter design theory. For the practical part of the paper, the algorithm of Levenberg-Marquardt is chosen as a local optimisation method. Whole process of automation is implemented in Matlab. An optimisation of a band-stop filter for Wi-Fi signals serves as a practical example. A Wi-Fi device communicating under standard 802.11b or 802.11g uses a specific channel which has frequency between 2.412 and 2.484 GHz. Therefore the goal is to design a band-stop filter which ideally does not transmit mentioned band of frequencies. The geometry of Jerusalem-cross serves as a structure to be optimized. Four design variables are defined for optimisation: the width and the height of a periodic
