Sistema de posicionamiento automático de antenas aplicado a tecnologías emergentes en las bandas ISM

Abstract

Abstract: The absorption of electromagnetic waves by the human body is a considerable problem when measuring the received signal power between a transmitting antenna and a receiving antenna, because this absorption by the human presence alters in some way the measurement readings, resulting in inaccurate and unreliable data when performing a power reception analysis. For this reason, the present work is executed with the objective of developing and implementing an automatic antenna positioning system controlled remotely and manually without the physical manipulation by a person, but through the controlled and precise movement from the use of stepper motors that position the antenna in degrees azimuth and elevation. The present positioning system is conformed by existing elements in the market of low cost and that do not interfere with the electromagnetic signals to obtain cleaner measurements in the spectrum analyzer of the UTPL laboratory and its operation is explained in detail with the purpose of understanding the system. The quality of this positioning system is that it does not affect the power measurements of the antennas obtained in the spectrum analyzer, reducing considerably the error when manipulated by a person in the telecommunications laboratory of the UTPL and in turn has a desired automatic technological performance.
