Claim:
1. An apparatus comprising: an antenna adapted to obtain a first signal in a first frequency band, and a second signal in a second frequency band, the antenna including a feeding portion and a ground portion; communication circuitry electrically connected to the feeding portion and adapted to communicate with a first object external to the apparatus using the first signal obtained from the antenna; sensor circuitry electrically connected to the antenna and adapted to detect a second object external to the apparatus using the second signal received from the antenna; an inductor electrically connected between the sensor circuitry and the antenna, and adapted to electrically open the sensor circuitry with the antenna with respect to the first signal, or electrically connect the sensor circuitry with the antenna with respect to the second signal; and a capacitor electrically connected between the ground portion and a ground of the apparatus, and adapted to electrically open the ground portion from the ground with respect to the second signal, and electrically connect the ground portion with ground with respect to the first signal.
