Abstract:
An antenna driving device for a mobile communication terminal including a flat antenna and a receiver for receiving a radio signal through the flat antenna, the device comprising:a flat antenna driver for shifting a direction of the flat antenna by predetermined steps;an RSSI (Received Signal Strength Indicator) detector for detecting an RSSI value of the received radio signal for each step of the flat antenna;a position detector for detecting a position of the flat antenna;a memory for storing the RSSI value detected for each step and the associated positional information of the flat antenna; anda controller for controlling the flat antenna driver and the RSSI detector, for comparing the detected RSSI value and a reference RSSI value, and for shifting the direction of the flat antenna to a position having a highest RSSI value by controlling the flat antenna driver.
