Abstract
In this project, a metamaterial-inspired multiband antenna with a size of 32 × 22 × 1.6 mm3 is designed on FR4 dielectric material that operates at eight wireless standards with gain enhancement application. The antenna has electrical dimension of 0.2581 λ × 0.1775 λ × 0.0129 λ (32 × 22 × 1.6 mm3), at a lower resonant frequency of 2.42 GHz. The proposed design has slots with Quasi CSRR (complementary split ring resonator) and SRR (split ring resonator) cell, respectively. Antenna achieves octa-band resonant modes for IoT and wireless applications S-band WLAN, bottom C-band WAIC, WLAN, bottom X-band, superior X-band, bottom Ku-band, superior Ku-band and bottom K band with optimized radiation properties. By the implementation of the proposed frequency selective surface (FSS) with design, antenna gain is improved for the resonant bands.
