RESUMO:

This study discusses the use of conductive paints on glass and ceramic substrates in the manufacture of planar circuits with applications in antennas and frequency selective surfaces (FSS). In the development of the FSS structures, uniform rectangular arrays of crossed dipole patch elements were used. In the development of microstrip antennas, rectangular conductive patches were considered. Among the materials used to obtain the developed paints, the synthesis of nitrocellulose as the glue and cargo vehicle has been investigated (metal powder) to constitue the conductive film. As diluent, isopropyl alcohol, acetone, ethyl acetate and toluene were tested. The load initially used was graphite powder and subsequently electrolytic copper, to obtain a conductive paint with improved properties than the commercially available conductive paints.
