Abstract
An apparatus and method for estimating the direction of an RF signal is provided. The apparatus includes an antenna for receiving an RF signal. An electronic compass is configured to, as a pointing direction of the antenna is varied, generate information about pointing directions and pointing angles corresponding to variations in the pointing direction of the antenna. A control unit determines RSSI values at respective pointing angles of the antenna based on a received signal of the antenna and information of the electronic compass depending on the variations, extracts a maximum RSSI value from the RSSI values at respective pointing angles, and stores the maximum RSSI value and a pointing direction corresponding to the maximum RSSI value. A display unit displays the RSSI values at the respective pointing angles and a trajectory of the RSSI values at respective pointing angles under control of the control unit.
