Patent ID: 7994989

Claim:
A handheld device with switchable signal receiving modes, comprising: a telescopic antenna, for being adjusted to a first length and a second length; a telecommunication transceiver module, for transmitting and receiving a signal of a first frequency via the telescopic antenna when the telescopic antenna is adjusted to the first length, and transmitting and receiving a signal of a second frequency via the telescopic antenna when the telescopic antenna is adjusted to the second length; a satellite signal module, for receiving a satellite signal via the telescopic antenna when the telescopic antenna is adjusted to the second length; and a switch circuit, for receiving a switch signal, and electrically coupled to the telescopic antenna, wherein when the telecommunication transceiver module is electrically coupled to the telescopic antenna, the switch circuit adjusts the telescopic antenna to the first length for the telecommunication transceiver module to transmit and receive the signal of the first frequency, and adjusts the telescopic antenna to the second length for the telecommunication transceiver module to transmit and receive the signal of the second frequency, or the switch circuit electrically couples the telescopic antenna to the satellite signal module when receiving the switch signal, and adjusts the telescopic antenna to the second length for the satellite signal module to receive the satellite signal.
