Development of reconfigurable FSS for 2.4 GHZ application

Given the current demand for telecommunications systems, frequency selective surfaces, active and passive FSS, have attracted the attention of several research groups due to their numerous applications, such as antenna reflectors, efficient windows, smart walls, among others. Against this backdrop, this paper presents the development of a reconfigurable frequency selective surface based on the four-arm star geometry for application in the 2400-2483.5 MHz band of the IEEE 802.11b/g/n (Wi-Fi) and IEEE 802.15 (Bluetooth) standards. The PIN diode was used as the switching element. Numerical results are presented, obtained using the commercial software ANSYS Designer, which is based on the Method of Moments, MoM, and experimental results, showing good agreement between them.
