    Sistema didáctico para la obtención automática de patrones de radiación de antenas en las bandas de 1 GHZ basado en detectores RMS de campo eléctrico
    (2017) Jaramillo Pizarro, Gino Geovanny; Araujo Pacheco, Alcides Fabián
    The Faculty of Engineering requires a didactic system that allows to obtain the radiation patterns of antennas that are within the range of 1 to 6 GHz. Thanks to the technological advances that have been developed through the current times to the power detectors, it became possible to develop the requested system, which was updated with various forms, methods and components that allowed the measurement of signals received by an antenna, providing an output RMS Voltage proportional to the value of the power received, which can be processed by the equation presented by the power detector to obtain a power value proportional to the output voltage value of the detector. The didactic system consists of programs developed in two different software known as LabVIEW and Matlab, the goal is to be created independent systems, for example, the National Instruments PXI, which is responsible for generating signals that are transmitted through a of the antennas placed in the transmitter support, in addition to the main programs, the mechanical part was designed which is complemented with the control of the support that contains the receiving antenna, and makes movements in the pickups in the mentioned frequencies in the beginning, the measurements realized enters an Arduino Mega 2560 that is in charge of sending data and receive values or orders to control the movements of the support that contains the antenna, and finally this values can be processed in each program and the expected results are visualized. In the system it must be considered that it is configured to perform measurements at each step, the initially configured step is 10 °, but it can be programmed to make measurements in steps of 1 ° or the distance at which it is desired to be measured take the steps, in order not to lose information and present more real data.
