ABSTRACT:
A miniaturized planar antenna of digital television comprises an insulation plate a metal radiator combined with a first surface thereof, a metal grounding element connected to a second surface thereof and a metal parasitic element. The metal radiator has a meander line portion and the metal parasitic element also has a meander line portion and is corresponding to a position of the metal radiator; the transmission efficiency of digital television signals can be elevated by broadening an electromagnetic signal receiving bandwidth of the antenna by means of the metal parasitic element.
