Mobile telephone capable of automatically switching antenna according to user's hand position

A mobile communication device, comprising:

• a first antenna configured to transmit and receive RF signals;
• a first capacitive sensor adjacent to the first antenna;
• a second antenna configured to transmit and receive RF signals;
• a second capacitive sensor adjacent to the second antenna;
• a sensing circuit in communication with the first capacitive sensor and the second capacitive sensor, the sensing circuit being configured to determine the position of a user's hand relative to the first antenna or the second antenna in response to sensing signals received from the first capacitive sensor and the second capacitive sensor;
• and
• an antenna switching circuit configured to select the first antenna or the second antenna to transmit and receive RF signals to enable wireless communications in response to the position of the user' hand relative to the first antenna and the second antenna as determined by the sensing circuit.
