Highly Selective, Closely Spaced Triple-Band Frequency Selective Surface for the Intensification in the Performance of WiMax and WLAN 2.5/3.5/5.5 GHz

摘要

With the widespread keenness of the Internet of things in the upcoming future and the sprouting of 5G communication systems, predominantly in residential areas, the number of WLAN and WiMax connected devices may increase exponentially. But due to several factors like path loss, propagation effects and interference led to signal degradation. WiMax and WLAN have used at different ranges of bands. However, these bands suffer from large attenuations, so a band-pass frequency selective surface has been proposed in the paper that led to the intensification in the transmission of WiMax and WLAN signals to reduce the effect of path loss. A single-sided FR-4 substrate has integrated with the square and three decagon elements which results in triple-band (2.5, 3.5 and 5.5 GHz) characteristics. The single-sided substrate dielectric constant is 4.4 with loss tangent 0.025 and thickness 1.6 mm. With respect to different incident angles, offered structure had excellent band-pass response. For evaluating the performance, the CST Microwave computer simulation is used.
