RESUMEN
En este trabajo se presenta un procedimiento para estimar la diversidad espacial en ambientes electromagnéticos de multitrayectorias, utilizando una antena de dos elementos (combinación dipolo aro-capacitor). La diversidad espacial se determina a partir del ángulo de incidencia de las señales electromagnéticas que llegan a la antena y de los coeficientes de correlación. El ángulo de incidencia permite también identificar las componentes de campo electromagnético, lo que muestra que la antena de dos elementos es una herramienta útil para el análisis de multitrayectorias, lo cual se prueba experimentalmente.
Palabras clave: Multitrayectorias, diversidad espacial, ángulo de incidencia.
ABSTRACT
This paper presents a procedure to estimate the spatial diversity in electromagnetic environments of multipaths, using an antenna of two elements (combination dipole hoop-capacitor). The spatial diversity is determined from the angle of incidence of electromagnetic signals arriving at the antenna and from correlation coefficients. This angle also allows to identify the components of the electromagnetic field, which shows that the two elements antenna is a useful tool to analyze multipaths, which is tested experimentally.
Keywords: Multipaths, spatial diversity, angle of incidence.
