| 摘要 |
The present invention relates to a power coupler for hyperfrequency signals. The single-section coupler with microstrip lines comprises a dielectric substrate, a main line and a secondary line comprising a coupling section, the lines being deposited on the substrate, the main line being substantially rectilinear and uniform over its entire length, the coupling section comprising a protuberance at each of its ends, the protuberances being interlinked by a portion of conductive line of which the section, the shape and the disposition are adapted to minimize the coupling between said portion and the main line relative to the coupling made between the protuberances and the main line. The invention applies notably to the measurement of the power of a signal passing through a transmission line.
