This summary aims to propose a Frequency Selective Surface (FSS) capable of filtering multiple frequency spectra. In telecommunications, the use of equipment operating in different frequency bands is becoming increasingly common, resulting in signal saturation. Therefore, this article aims to propose an FSS capable of filtering spectra that operate in the Wi-Fi WLAN range of 2.4 GHz and Bluetooth technology, as well as operating in the 5G technology range (3.4 GHz to 3.7 GHz), and finally, in the Safety Band (5.850 GHz to 5.925 GHz).
