Antennas are receiving attention for the future of wireless communication because of their wideband and multiband capabilities. In this paper, an attempt has been made to compare the performance of silver nanoparticle ink (Ag NP ink) used for patch antennas with the traditional copper patch antenna. The Millimeter Wave patch antenna is designed and simulated to evaluate various parameters like return loss, VSWR, radiation pattern, gain, band width and 3D polar plot using Ansoft High Frequency Structure Simulation (HFSS) software. FR-4 with relative permittivity of 4.4and dielectric loss tangent of 0.02 is used as a substrate for the antenna. The designed rectangular microstrip patch antenna is analyzed using transmission line feed technique at 24 GHz range. Various parametric results show that silver nanoparticle ink (silver NP ink) is similar to copper patch providing a comparable voltage standing wave ratio (VSWR), band width and radiation pattern further there has been observed an increase in return loss and gain of silver NP ink. Thus, the silver NP ink can be good alternative to copper conductive patch antennas.
