具有电容式传感器和近场通信的用于机动车的门把手装置
摘要：
用于机动车的传感器装置，其具有电路板(10；20；40)，在电路板上构造有电容式传感器的传感器电极(13；22；44)。感应式近场传输装置构造有近场传输线圈(11；21；30)，该近场传输线圈在电路板(10；20；40)上具有至少一个线匝。近场传输线圈(11；21；30)和传感器电极(13；22；34)相对彼此布置成使得传感器电极位于近场传输线圈的被线匝包围的内部区域中，其中，传感器电极具有纵长延伸的中间导体(14)和多个从中间导体延伸出的分岔导体(15)。分岔导体间隔开地从中间导体出发，使得分岔导体(15)仅经由中间导体(14)电气耦合，并且分别成对地朝向彼此背对的侧地布置在中间导体上，从而对于每个分岔导体而言均有配属的分岔导体构造在中间导体的每个背对的侧上。
摘要（英）：

The invention relates to a sensor device for a motor vehicle, having a printed circuit board (10; 20; 40), on which a sensor electrode (13; 22; 34) of a capacitive sensor is formed. An inductive near-field transmission device is formed with a near-field transmission coil (11; 21; 30), which has at least one turn on the printed circuit board (10; 20; 40). The near-field transmission coil (11; 21; 30) and the sensor electrode (13; 22; 34) are arranged relative to each other in such a way that the sensor electrode lies in the inner region of the near-field transmission coil surrounded by the turn, the sensor electrode having an elongate central conductor (14) and a plurality of branch conductors (15), which extend from the central conductor. The branch conductors extend out from the central conductor with spacing in such a way that the branch conductors (15) are galvanically coupled exclusively by means of the central conductor (14) and are arranged on the central conductor on opposite sides in pairs such that, for each branch conductor, an associated branch conductor is formed on the opposite side of the central conductor.
