VEHICLE COMMUNICATION APPARATUS

A vehicle door handle driving device (50, 60, 65) connected to an antenna (21) and a DC driving detection member (30) capable of detecting approach or touch of a person, which are connected in parallel, through first and second connection wires (W1, W2), wherein the first connection wire is constantly connected to a first positive DC power supply (+B), and the second connection wire is connected to a ground for a period during which the antenna is not driven, the vehicle door handle driving device includes: a booster capacitor (56) whose first terminal is connected to the first DC power supply; and an inverter (INV) connected to the second terminal of the booster capacitor, connected to a second positive DC power supply and the ground, generating an AC voltage having a resonance frequency of the antenna, and outputting the generated AC voltage to the first and second connection wires.
