Abstract: Provided is a T-DMB receiver and receiving method using a human body as an antenna. The T-DMB receiver includes: an electrode making contact with a human body; a low frequency amplifier receiving via the electrode a current flowing through the human body due to a DMB broadcasting signal emitted by a terrestrial relay station and amplifying the received current; and an impedance matching circuit located between the electrode and the low frequency amplifier and matching an impedance of the human body with an impedance of the low frequency amplifier. Accordingly, a T-DMB receiver easy to carry without a separate antenna can be implemented.
