Title (EN) ANTENNA SYSTEM AND METHOD FOR DETERMINING A TRANSIT OF A MOVABLE OBJECT THROUGH A DETECTION PLANE
(FR) SYSTÈME D'ANTENNE ET PROCÉDÉ POUR DÉTERMINER UN TRANSIT D'UN OBJET DÉPLAÇABLE À TRAVERS UN PLAN DE DÉTECTION
Abstract:
(EN) Embodiments relate to a concept for determining a transit of a movable object (11) through a detection area within a detection plane (22), comprising providing, by means of at least one exciter antenna (9), an exciting electromagnetic field (12), wherein the exciting electromagnetic field (12) or at least one spatial component thereof has a field strength above a field strength threshold in the detection area, wherein the exciting elec¬ tromagnetic field (12) is capable of exciting the movable object (11) to emit an electro- magnetic response signal (44a, 44b) comprising information on a position of the movable object (11); and receiving, by means of at least one sensor antenna (4a-d) comprising a magnetic core (31), the electromagnetic response signal (44a, 44b), wherein the at least one magnetic core (31) is positioned in a region (27) of the exciting electromagnetic field (12) where the field strength of the exciting electromagnetic field or the at least one spa- tial component thereof is below the field strength threshold.
(FR) Des modes de réalisation de l'invention portent sur un concept pour déterminer un transit d'un objet déplaçable (11) à travers une zone de détection à l'intérieur d'un plan de détection (22), comprenant la fourniture, au moyen d'au moins une antenne excitatrice (9), d'un champ électromagnétique d'excitation (12), le champ électromagnétique d'excitation (12) ou au moins une composante spatiale de ce dernier possédant une intensité de champ supérieure à un seuil d'intensité de champ dans la zone de détection, le champ électromagnétique d'excitation (12) étant capable d'exciter l'objet déplaçable (11) pour émettre un signal de réponse électromagnétique (44a, 44b) comprenant des informations sur un emplacement de l'objet déplaçable (11); et la réception, au moyen d'au moins une antenne de capteur (4a-d) comprenant un noyau magnétique (31), du signal de réponse électromagnétique (44a, 44b), ledit noyau magnétique (31) étant positionné dans une région (27) du champ électromagnétique d'excitation (12) où l'intensité de champ du champ électromagnétique d'excitation ou ladite composante spatiale de ce dernier est inférieure au seuil d'intensité de champ.
