In this paper, a novel folded metal-plate monopole antenna is presented for indoor digital television (DTV) signal coverage in the 454-1300 MHz band. The proposed antenna consists of a folded metal-plate with two asymmetrical bevels and a shorted pin connecting the metal-plate with a ground plane. The folded structure extends the lower frequency band and reduces the height of the antenna for better application to DTV. Experiment results show that the antenna achieves a bandwidth for |S11| < -10 dB ranging from 454 MHz to 1300 MHz and shows stable radiation patterns in three coordinate planes.
