Abstract: A navigation apparatus and a navigation method using an RFID scheme are provided to recognize precisely a current position and a progress direction by utilizing position and wireless signal information of an RFID tag using a directional antenna. A navigation apparatus using an RFID scheme includes an antenna(110), an RFID(Radio Frequency IDentification) reader(120), and a controller(130). The antenna unit having directional antenna which has different directivity receives at least one wireless signal from at least one RFID tag. The RFID reader converts the wireless signal into digital RFID tag information, measures received strength of the wireless signal, and provides the converted RFID tag and received strength information. The controller determines current position based on the received strength information, compares the RFID tag information from the RFID reader with RFID tag lists which are installed at heading direction, reads RFID tag information based on the comparison, and determines a heading direction based on the read RFID tag information.
