Vehicle door handle assembly with antenna circuit
First Claim
1. A vehicular door handle system, said door handle system comprising:
- a door handle assembly for a door of a vehicle, said door handle assembly configured to mount at a handle region of the vehicle door;
said door handle assembly comprising a door handle portion that is graspable by a user to open the vehicle door;
said door handle assembly comprising an antenna circuit for a passive entry system of the vehicle, said antenna circuit comprising at least an inductor in series electrical connection with a capacitor;
wherein said antenna circuit comprises a resistor in series electrical connection with said inductor of said antenna circuit and said capacitor of said antenna circuit;
wherein said series electrical connection comprises one of (i) said resistor being disposed between said inductor and said capacitor of said antenna circuit and (ii) said resistor not being disposed between said inductor and said capacitor of said antenna circuit; and
wherein said resistor functions to reduce the Q factor of said antenna circuit.

Abstract
A vehicular door handle system includes a door handle assembly for a door of a vehicle. The door handle assembly includes a door handle portion that is graspable by a user to open the vehicle door. The door handle assembly includes an antenna circuit for a passive entry system of the vehicle. The antenna circuit includes at least an inductor in series electrical connection with a capacitor. The antenna circuit includes a resistor in series electrical connection with the inductor of the antenna circuit and the capacitor of the antenna circuit. The series electrical connection includes one of (i) the resistor being disposed between the inductor and the capacitor of the antenna circuit and (ii) the resistor not being disposed between the inductor and the capacitor of the antenna circuit. The resistor functions to reduce the Q factor of the antenna circuit.
