Artigo A new conductive Ink for microstrip antenna and bioinspired FSS designs on glass and fiberglass substrates(Scielo, 2019-06-19) D´Assunção, Adaildo Gomes; Oliveira, João Bosco Lucena; Mesquita, Marcelo David Silva de; Batista, Yuri Max VieiraThis paper describes an investigation of the possibility of using a new conductive ink, instead of copper clad laminates, in the manufacturing of microstrip patch antennas on glass and fiberglass substrates and of bioinspired frequency selective surfaces (FSSs) on fiberglass substrates for wireless communication systems. The new conductive ink is developed using synthesized nitrocellulose which, in ethyl acetate solution, works as a bonding agent and carrier for the formation of a conductive film. The load used in the fabrication process is silver metallic powder. Simulation and analysis are performed using Ansoft Designer and HFSS softwares. Microstrip antenna and FSS prototypes are fabricated and measured for comparison purpose. An agreement is observed between simulation and measurements results
