PURPOSE: An antenna system for T-DTV is provided to reduce the length of an antenna by having an active antenna which includes an amplification function without additional amplifier. CONSTITUTION: An antenna(10) receives T-DTV broadcasting frequency full band. An LNA(Low Noise Amplifier)(20) is attached to the antenna in order to minimize signal transmission loss. The LNA amplifies a signal of low output level of the antenna. The antenna and the LNA are divided into two bodies. The antenna and the LNA are composed of one antenna system.
