Zusammenfassung:PURPOSE: A device for supplying and controlling a receiving/transmitting circuit current of a cellular phone with a diversity antenna, is provided to extend life of a battery, by supplying current with only a main receiving circuit, during standing by for receiving, to prevent unnecessary use of the battery's current. CONSTITUTION: A device for supplying and controlling a receiving/transmitting circuit current of a cellular phone with a diversity antenna, comprises a main receiving circuit power, a diversity receiving circuit power(90), a transmitting circuit power(100), and a power controller(110). The diversity antenna has a main antenna(10), a diversity antenna(20), a main receiving circuit(30), a diversity receiving circuit(40), and a transmitting circuit(50). The main receiving circuit power, the diversity receiving circuit power(90), and the transmitting circuit power(100) supply current, by connecting to the main receiving circuit(30), the diversity receiving circuit(40), and the transmitting circuit(50) separately. The power controller(110) supplies current with only the main receiving circuit(30) during standing by for receiving, and with the main receiving circuit(30), the diversity receiving circuit(40), and the transmitting circuit(50) during calling.
