An antenna apparatus for receiving terrestrial DMB by using a car window's heat coil is provided to receive a terrestrial DMB signal through the heat coil of the car so that a car owner can reduce unnecessary cost because the car owner has no need to purchase a separate terrestrial DMB receiving antenna. An antenna apparatus for receiving terrestrial DMB(Digital Multimedia Broadcasting) by using a car window's heat coil includes the car window's heat coil(1), an RF(Radio Frequency) module(10) and a main module(20). The RF module is installed in the power line of a side of the car window's heat coil, removes noise after receiving a terrestrial DMB signal, selects and outputs the signal of which the noise is removed by channel. The main module has an AGC unit(24) which performs the AGC(Auto Gain Control) of the terrestrial DMB signal outputted from the RF module and outputs the terrestrial DMB signal to a terrestrial DMB receiver(30). |
