RESUMO:

The Information Age has brought to the modern world an ever-increasing demand for more reliable wireless communication systems with greater information transmission capabilities. Allied to this, it has been observed that the society has presented an increasing necessity for radiofrequency transmission and reception devices, apparatuses, or equipment with smaller sizes. In addition, new satellite systems technologies have been developed, such as nanosatellites, with extremely small dimensions, leading to a constant need for size optimization and manufacturing costs reduction. Planar microstrip antennas have been widely used in wireless mobile communications systems in the microwave and millimeter wave ranges since the mid-1970s. To support the miniaturization of transmitter and receiver devices, it is necessary to develop antennas of increasingly smaller dimensions which can be realized through various techniques. This doctoral thesis presents the use of a new technique for the design of compact microstrip planar antennas, meeting the society's current demands and wishes. Specifically, the proposed technique combines the insertion of vias and Koch fractal contours in microstrip antenna patches into the design and synthesis of planar microstrip antennas that can be used in wireless communication systems and, particularly, in the Brazilian space program, in the development of nanosatellite projects carried out by the National Institute of Space Research - INPE / MCTI.
