This work presents the development of a reconfigurable frequency selective surface (RFSS) for application in 2400-2483.5 MHz band, standard IEEE 802.11b/g/n (Wi-Fi). The proposed RFSS is based on four-arms star geometry and PIN diodes were used as switching elements. In initial design, numerical measured results, especially y polarization, diode on-state, shown difference 15% resonant frequency...

With the increase in usage of electromagnetic devices, interference increased many folds. Frequency Selective Surface (FSS) provide effective shielding from unwanted frequency ranges. A thin, conformal band-stop FSS is presented this research that provides properties X-band. The acts as a band stop filter at 10 GHz. proposed has 54.7% fractional bandwidth. design dimensions 6.79 x 0.127 milimet...
