In this book, a systematic approach for the design, fabrication and testing of antennas using Ink Jet Printing Technology (IJPT) is presented. The antennas are fabricated using DMP-2800 Dimatix FujiFilm Material Printer and Sliver Nano Particles (SNP) ink. The 3D electromagnetic simulation softwares CST MWS and HFSS are used to design the antennas reported in this book . In addition to simulation, measurements of the antenna parameters have been performed using a vector network analyzer and UALR’s anechoic chamber. An initial antenna design based on the traditional square patch geometry is involved as a benchmark to characterize the entire approach adopted to design any antenna geometry. The systematic approach for the manufacturing process includes the optimal number of printed layers, curing temperature and curing time, to achieve high electrical conductivity.
