The objective was to improve parameters to make the radiation of the proposed antenna more directive. To this aim, the development is focused on reducing the squint of the central radiation beam and the side lobe level (SLL), as well as increasing the gain compared to a Conventional AVA. To achieve the objective, using an optimized design. The proposed antenna with or without a lens reached the target with a squint of -2.0 degrees, at 3.90 GHz the antenna with a lens achieved better gain (9.42 dB), but with a greater reduction in SLL of -10.73 dB compared to the lens less antenna. The results were obtained with computational electromagnetic simulations and experimental measurements.</p> Raimundo Eider Figueredo Alexandre Maniçoba de Oliveira João Francisco Justo Copyright (c) 2023 Journal of Mechatronics Engineering 2023-11-05 2023-11-05 6 1 1 9 10.21439/jme.v6i1.112 http://200.129.18.8/index.php/jme/article/view/113 <p>Industrial processes, over the years, need to be modernized to reduce costs and maintain product quality. In this context, new tools or techniques have been developed for such an event to further improve industrial processes and the quality of the manufactured product. This paper refers to the application of a graphical and mathematical modeling tool, in this case, the Colored Petri Net (CPN), applied to a corrective maintenance process of a conical machine in the textile industry. That is, the<br />corrective maintenance process is modeled as a discrete event system for decision-making to identify which task must be performed to perform corrective maintenance. It also presents the operation of CPN for the described process, the general concepts of maintenance applied to the textile industry, the theory about PN, as well as the modeling of the process. The results show the mathematical model of the PN and the CPN graph, modeled for the maintenance process, which will facilitate the understanding of the maintenance process, as well as solve future problems more quickly and with quality. Finally, it is concluded that the model carried out can be used as a decision-making system to facilitate the corrective maintenance process.</p> Josias Guimarães Batista Maria Liliane Alves da Silva Rejane Cavalcante Sá Cícero Roberto Oliveira Moura Copyright (c) 2023 Journal of Mechatronics Engineering 2023-12-21 2023-12-21 6 1 10 22 10.21439/jme.v6i1.113
