Abstract
This paper deals with the study of multiband printed antenna coated with silver nanomaterial to obtain better performace in the antenna characteristics. The techniques adopted in the study are etcing of novel patch with definitive dimensions as the fucntion of chosen operating wavelength at 8 GHz as the design constraint along with defective ground layer to minimize the propogation losses in the antenna. From the results, it is clear that, the antenna obtained 61.20% improvement in bandwidth for the fabricated Multiband Printed Antenna with Defected Ground Structure (MPA DGS) and 32.10% bandwidth improvement for Nanomaterial Coated Multiband Printed Antenna with Defected Ground Structure (NCMPA-DGS)(NCMPA-DGS) with quad-band characteristics suitable for Wireless applications. The proposed antennas are compact in nature which has also achieved good radiation characteristics.
