RESUMO:

The rapid technological advances have enabled the emergence of a growing number of applications using wireless communication systems. Flexibility, reduced implementation time and infrastructure deployment costs, as well as reliability and robustness are characteristics that have required the use of this type of communication system. Similarly, the radio frequency planar technology has attracted the interest of many researchers in the development of circuits for wireless communication systems due to its specific features such as small size, low weight and manufacturing cost and ease of integration with other parts of the circuit (without considerable hardware changes), among others. The constitutive nature of planar antennas is especially suitable for use in wireless communication systems. In particular, microstrip antennas are highlighted because of their numerous applications in radar, telemetry, navigation systems, biomedical systems, mobile communications, satellite communications and global positioning system (GPS), among others. Depending on the geometry and type of the used feeding line, antennas may be developed for many radiation applications with different polarization and radiation diagram forms. The resonant modes excited in the antenna depend, among others, of the characteristics of the conductors and dielectric elements, of the type and positioning of the employed feeding line structure and the used impedance matching circuit. A suitable impedance matching circuit is a fundamental prerequisite for a good microstrip antenna design, as it allows most of the power supplied by the line to be delivered to the antenna and, conversely, most of the power received by the antenna to be transmitted to the transmission line. This dissertation proposal is focused on the development of new impedance matching techniques between the transmission line and the antenna.
