Resumen
This monograph is a study carried out for the design and manufacture of a helical antenna, and the use of a radio frequency amplifier in order to improve the operational coverage conditions for a Remotely Piloted Aircraft System of the quadcopter type, which seeks to extend the coverage of the telemetry transmission of the radio control used for its operation in flight. This work focuses on two topics that are related to the antenna design. The first one explains the theory related to the antenna frequency operation, the type of polarization of a helical antenna, its radiation pattern, the operating field region and the impedance associated with the antenna design. Likewise, we worked on the parametric simulation of the antenna in the CST Studio software, thanks to this simulation we studied the variations of the spiral separation and the diameter of the antenna, which are based on the design of the real antenna. The second section focuses on the construction and fabrication of the helical antenna. In this section we can detail the corrections to its impedance with the Smith chart, since in this way it is possible to obtain an improvement in the propagation efficiency and improve the results in the S11 parameters. Along with the improvement of the operational coverage, a Radio Frequency amplifier is selected to improve the dBm of the ground transmitter. This component is compatible with
