Patent

CA 2479173

An apparatus and method for coupling energy from a transmission line (100) is provided. The apparatus includes a contact (104) designed to "tap" into an inner conductor (102) of the transmission line (100) through an aperture in an outer conductor of the transmission line. A portion of the contact (104) may be coiled (e.g., a spring) and the coil's characteristics may be varied to control the insertion loss and coupling loss of the apparatus. For example, the wire size, coil diameter, number of turns, and pitch design of the coil may be controlled. The apparatus may also include a secondary transmission line connected to the coil and the secondary transmission line may allow additional control over the coupled energy.

L'invention concerne un dispositif et un procédé servant à coupler l'énergie d'une ligne de transmission. Le dispositif comprend un contact conçu pour être branché sur un conducteur intérieur de la ligne de transmission (100) par une ouverture pratiquée dans un conducteur extérieur de la ligne de transmission. Une partie du contact peut être spiralée (une bobine, par exemple) et les caractéristiques de la bobine peuvent être modifiées de manière à contrôler l'affaiblissement d'insertion et l'affaiblissement de couplage du dispositif. Par exemple, les dimensions du fil, le diamètre de la bobine, le nombre d'enroulements et le pas de la bobine peuvent être modifiés. Le dispositif peut également comprendre une ligne de répartition reliée à la bobine, permettant de contrôler davantage l'énergie couplée.
