Gain Enhancement of Metamaterial-Inspired Multiband Antenna for Wireless Applications

In this project, a metamaterial-inspired multiband antenna with a size of 32 x 22 x 1.6 mm(3) is designed on FR4 dielectric material that operates at eight wireless standards with gain enhancement application. The antenna has electrical dimension of 0.2581 lambda x 0.1775 lambda x 0.0129 lambda (32 x 22 x 1.6 mm(3)), 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.
