Patent ID: 7541983

Claim:
A planer antenna for receiving digital television signals comprising a printed circuit board; a body being a conductive pattern formed on the printed circuit board, receiving an electromagnetic wave signal of television programs, and having a tip; a feeding port being a signal output of the body and being formed at the tip; and a line of longitudinal symmetry emanating from the tip, along which a sequence of shapes being formed toward the tip and comprising a trapezoid segment having a base edge being furthest from the tip; two side edges; and a parallel edge; a hexagon having a long transverse edge corresponding to and being formed adjacent to the parallel edge of the trapezoid and having two ends a short transverse edge being shorter than the long transverse edge, being parallel to the long transverse edge and having two ends; two short side edges being formed respectively adjacent to and corresponding to the ends of the long transverse edge of the hexagon; and two long side edges being longer than the short side edges, being formed respectively between the short side edges of the hexagon and the short transverse edge of the hexagon; and a diamond segment having a connecting edge corresponding to and being adjacent to the short transverse edge of the hexagon segment; two short edges being formed respectively adjacent to the connecting edge of the diamond-like segment; and two long edges being formed respectively between the short edges of the diamond segment and the tip of the body; and two apexes being defined respectively between the corresponding long and short edges of the diamond segment; an interface being rectangular, conductive pattern, coupling with the body at the feeding port, receiving signals form feeding port, being formed on the circuit board near the feeding port and having two longitudinal edges; a broken transverse edge being formed aligned with the apexes of the diamond segment of the body; a breach being a non-conductive and being formed on the broken transverse edge of the interface separating to the body and the feeding port from the interface; a second transverse edge being parallel to the base edge of the trapezoid; and an output port being formed on the interface.
