Abstract

L'invention concerne une poignée de porte (10) pour une pièce mobile (101), telle que par exemple une porte, un clapet ou un couvercle d'un véhicule (100), équipée d'une unité électronique (15) qui sert au moins à la communication de données avec un système côté véhicule (103) ou avec un appareil portatif mobile (52), l'unité électronique (15) étant disposée dans un évidement (11) dans la poignée de porte (10). Selon la présente invention, l'unité électronique (15) comporte au moins une antenne (17) et un détecteur de proximité capacitif (18), l'antenne (17) servant en particulier à la communication de données sans fil avec l'appareil portatif mobile (52) tandis que le détecteur de proximité capacitif (18) est approprié pour la détection, par une technique de mesure, d'une approche d'un opérateur.
