Title
(EN) ANTENNA ASSEMBLY FOR SUBSURFACE METER PITS
(FR) ENSEMBLE ANTENNE POUR PUITS DE MESURE SOUTERRAINS
Abstract
(EN) An antenna assembly (10) for subsurface utility metering equipment includes a disk-shaped radiating element (50) which is connected through a wire (51) having a self-inductance to a capacitor (C) and then to a ground plane (41) and a connector (31) for a coaxial cable (30) to provide an LC circuit for impedance matching of the antenna assembly (10) to a transmitter.
(FR) L'invention concerne un ensemble antenne (10) destiné à un appareil d'utilité publique permettant d'effectuer des mesures souterraines, qui comprend un élément rayonnant (50) en forme de disque, connecté par l'intermédiaire d'un fil (51) à auto-inductance à un condensateur (C), à un plan à la terre (41) et à un connecteur (31) de façon à ce qu'un câble coaxial (30) fournisse un circuit LC permettant d'établir une correspondance d'impédance entre l'ensemble d'antenne (10) et un émetteur-récepteur.
