<p>Provided is an antenna system (300) for terrestrial broadcasting. The antenna system has a dipole antenna probe (310) receiving a broadcast signal, a signal amplifier(330) amplifying the received broadcast signal, an antenna matching unit (320) matching impedances between the antenna probe and the signal amplifier, an output matching unit (340) matching impedances between an output signal of the signal amplifier and an input terminal of a broadcast receiver (370) to which the output signal is fed, and a bias extractor (350) converting power received from the broadcast receiver into power needed for driving the signal amplifier and supplying the converted power to the signal amplifier.</p> |
