Abstract

The invention discloses a two-channel automobile door handle sensing antenna which comprises a shell, an adhesive layer, a PCB (printed circuit board), a pole piece layer and a wire harness. The adhesive layer covers the upper surface of the PCB, the pole piece layer covers the lower surface of the PCB, the adhesive layer, the PCB and the pole piece layer are arranged in the shell, the adhesive layer is used for covering and sealing welding spots on the PCB, an inductive sensor is arranged on the PCB, one portion of the wire harness is arranged on the PCB and connected with an output end of the inductive sensor, the other portion of the wire harness is arranged outside the PCB, the pole piece layer is connected with an input end of the inductive sensor, and the inductive sensor is used for detecting whether an object enters a detecting range or not. The sensing antenna is applicable to automobile PE (passive entry) functions, super-high in sensitivity and adaptive function and strong in interference resistance, and can be applied to various complex environments.

Description

technical field [0001] The invention relates to the technical field of automobile electronic control, in particular to a dual-channel automobile door handle induction antenna. Background technique [0002] The basic principle of capacitive sensing is to use the charging and discharging of capacitors and the principle of series and parallel connections of capacitors. The series connection of capacitors and capacitors will reduce the total capacity, and the parallel connection of capacitors and capacitors will increase the total capacity. Any conductive object can be regarded as an equivalent capacitance relative to the earth, for example, a human hand and the earth are equivalent to a capacitance of about 5pf. When the equivalent capacitor is close to or touches another capacitor, coupling will occur, increasing the total capacity and prolonging the charging and discharging time of the original capacitor. Through this change, the approach or touch of the hand can be detected...
