A Novel Triple Band Pass Frequency Selective Surface for the Proliferation the Performance of WiMax and WLAN 2.5/3.5/5.5 GHz

Among the upcoming wireless technologies, WiMax and WLAN provide soaring speed communication with full coverage. However due to assured factors like path loss, interference, and coverage area led to signal degradation. WiMax and WLAN have used different range of bands. But these bands suffer large path loss, so a band-pass frequency selective surface has been projected in this paper which led to escalation in the transmission of WiMax signal to reduce the effect of path loss. In the proposed design, a single-sided FR-4 substrate is inbuilt with the square and three elements that led to triple-band characteristics at 2.5, 3.5, and 5.5 GHz. The dielectric constant of substrate is 4.4, and dimension of substrate is 0.166 lambda x 0.166 lambda. Further, this paper has been realized with simulated results in CST Microwave Studio.
