RESUMO:

Organic materials are used in several technological applications, such as in mechanics and bioelectronics. However, these materials are still little used in telecommunications, and in particular in the development of microwave integrated circuits. This work proposes the analysis and characterization of carnauba wax for applications in wireless communication systems operating in both S and X bands. The chemical properties are characterized by X-ray diffraction (XRD) and Fourier-transform infrared (FT-IR) spectroscopy. The mechanical properties will be investigated by the Vickers microhardness test and scanning electron microscopy (SEM), while the electrical properties will be evaluated by means of relative permittivity, loss constant, ferroelectric hysteresis loop and dielectric spectroscopy. The performance of these measurements should indicate new applications for the investigated ceriferous material. Nevertheless, recent works have confirmed the possibility of applying this material in the manufacture of microstrip antennas, which confirms its suitability for the development of other microwave integrated circuits.
