Abstract
With a power supply provided for a smart antenna, whether the antenna is connected is determined according to whether the power supply is connected. When it is determined that the smart antenna is not connected, power supply to units related only to controlling of the smart antenna is stopped, whereby power saving is realized. Further, user's setting for discriminating kinds of antennas becomes unnecessary and, when a smart antenna is not connected, power supply for the same can be prevented.
