| This thesis deals with the characterization of folded-slot antennas based on design of experiment techniques. Several 24 factorial designs were used for the characterization of folded-slot antennas in a substrate with relative permittivity of 3.48 and a thickness of 0.762 mm. Five responses were chosen to be observed since they summarize the behavior of this antenna configuration. The five responses are the resonant frequency, the input impedance at resonance, the directivity on the air side, the directivity on the substrate side and the efficiency. A statistical analysis was performed in each of these responses and design guidelines were presented for each of the first three folded-slot antenna resonances. Regression models were obtained for predicting each of the responses. Matching techniques were found for each resonance, the most attractive is perhaps the 1st resonance, since it offers reduced size. |
