Patent ID: 8854114

Claim:
An antenna drive apparatus having a drive control unit and an antenna electrically connected to the drive control unit via a first connecting line and via a second connecting line, and driven by an AC signal supplied from the drive control unit at a first resonant frequency, comprising: a first driven member electrically connected to the drive control unit via the first connecting line and via the second connecting line in parallel with the antenna and driven by the AC signal supplied from the drive control unit at a second resonant frequency different from the first resonant frequency; a sensing member electrically connected to the drive control unit via the first connecting line and via the second connecting line in parallel with the antenna and driven by a DC signal supplied from the drive control unit, the sensing member being capable of sensing approach or contact of a person and configured to output a sensing signal indicating the fact that the approach or the contact has been sensed to the drive control unit via the first connecting line; and a stop mechanism configured to stop a function of the sensing member when the AC signal supplied to the antenna or the first driven member is sensed.
