Fabrication and Characterization of Multiband Printed Antenna with Defective ground Structure Coated with Silver Nanomaterial for Wireless Applications

Abstract

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