Resumo Inglês:

In this paper a truncated corner rectangular microstrip
antenna (TCRMA) is analyzed in the presence of carbon fiber
composite (CFC) material. Simplified carbon fiber composite
models are proposed and the analyses are performed by the
electromagnetic simulator Computer Simulation Technologies
(CST). Theoretical and experimental results of return loss, axial
ratio, input impedance and radiation pattern for the antenna
located on the aluminum and CFC plates are presented and
compared. The results show that the proposed models can be used
as a good approximation of the CFC sample and that the CFC
material is a feasible alternative instead of aluminum for antenna
applications on complex structures such as ships or airplanes.
