1. A planar antenna for receiving high definition television signals, which comprises:

  • a dielectric substrate having a first side and a second side disposed opposite the first side, the first and second sides respectively having first and second conductive patterns including segments functioning as antenna elements and forming respective first and second modified H-shaped patterns thereon, the first conductive pattern situated on the first side of the dielectric substrate of the planar antenna further having a first extended S-shaped segment, the second conductive pattern situated on the second side of the dielectric substrate of the planar antenna further having a second extended S-shaped segment, each of the first and second extended S-shaped segments comprising an S-shaped segment and an extended segment, the S-shaped segment comprising an elongated main portion and two sub-segments perpendicularly connected to ends of the elongated main portion;

    wherein each of the extended segments is perpendicularly connected to an end of each of the S-shaped segments and acts as a parasitic element for the planar antenna.
