Abstract :
The following paper is shown the design and the evaluation of four different types of dipole antennas with curved forms, optimized with the purpose to obtain the greater Maximum antenna´s Directivity modifying the parameters of form. The optimization method was a simple genetic algorithm (SGA) and the experimental results is presented to a fixed frequency of UHF, where the VSWR, the radiation pattern, the Maximum Gains and the magnitude of normalized printed current density of the different propose antennas is details.
