RESUMO:

This work presents the design, fabrication, and analysis of planar antennas using metamaterial cells, aiming to change their operational characteristics. Planar antennas are usually compact, which facilitates fabrication and integration, however, they have some limitations such as low or moderate gain and considerable losses at some frequencies. Thus, the use of planar antennas with metamaterials makes it possible to circumvent some of the limitations, in order to improve the performance of the antennas. In this work, two topologies of planar antennas will be analyzed, the quasi-Yagi Antenna and the Planar Inverted-F Antenna (PIFA). In addition, the large number of devices and standards operating at 2.4 GHz Industrial, Scientific, and Medical (ISM) band becomes it attractive for Radiofrequency Energy Harvesting (RFEH) applications, whose implementations of analyzed topologies as rectennas are also explored.
