RESUMO:

Nowadays there is a breakthrough in the aerospace area, telemetry system, remote sensing, radar system (tracking and monitoring), satellite communications systems and new technologies for voice and data communications. Thus, this work presents a study about microfitas antennas for 4 g, 5 g technologies with applications in the 28 GHz frequency and 60 GHz, resonator spiral loop for applications in UWB (Ultra Wide Band) with bands and rectangular and circular cylindrical antennas for telemetry and satellite operating in the range of 2 to 4 GHz in s. studies in antennas are made, such as: application of EBG structure (Electromagnetic Band Gap) on the substrate and the ground plan, using metamaterial substrate, application of DGS structures (Defected Ground Strutures) in land plan and arrangements, with the objective of obtaining improvement in the parameters, in particular gain and bandwidth. The analysis of the dimensions of the antennas are developed using the method of the Transverse transmission line (LTT) which is a method of rigorous analysis in the spectral domain. Various simulations and measurements of antennas proposals are carried out so that the measured values are compared with the simulated values, aimed at the validation of the prototypes. In the end, are presented suggestions for the continuation of this work.
