Title (EN) ANTENNA DIVERSITY FOR WIRELESS TRACKING SYSTEM AND METHOD
(FR) DIVERSITÉ D'ANTENNE POUR UN SYSTÈME ET UN PROCÉDÉ DE POURSUITE SANS FIL
Abstract: front page image
(EN)The present invention provides a solution to determine a real-time location of an object (100) in an indoor facility (70) utilizing the spatial and angular antenna diversity on a sensor (55). Specifically, the spatial diversity is achieved by placing a second antenna (250) a predetermined distance (which is greater than one-half of the wavelength) away from a first antenna (200). The angular diversity is obtained by placing the second antenna (250) at ninety degrees (perpendicular) angle of the first antenna (200).
(FR)La présente invention a pour objet une solution permettant de localiser en temps réel un objet dans une installation couverte en utilisant la diversité d'antenne spatiale et angulaire sur un capteur. Plus précisément, la diversité spatiale est obtenue en plaçant une seconde antenne à une distance prédéterminée (supérieure à la demi-longueur d'onde) de la première antenne. La diversité angulaire est obtenue en plaçant la seconde antenne à un angle de quatre-vingt-dix degrés (angle droit) de la première antenne.
