Patent ID: 7586456

Claim:
A DVB-T broadband antenna applied in a digital TV system, comprising: a dielectric substrate; a radiation conductor, disposed on the dielectric substrate, the radiation conductor having a first side and a second side, wherein the first side is adjacent to the second side, the first side is longer than the second side, and the second side has a first feeding point and a second feeding point for receiving a radio-frequency (RF) signal to generate a first resonant mode of the radiation conductor; and a feeding gap, having a first end located at the first side and a second end located at the second side, wherein the feeding gap divides the radiation conductor into a first sub-radiation conductor and a second sub-radiation conductor; wherein the first feeding point is located on the first sub-radiation conductor and the second feeding point is located on the second sub-radiation conductor; wherein the first end of the feeding gap is located at the first side such that the length of the second sub-radiation conductor is close to one-third of the length of the first side and a length of the second sub-radiation conductor is substantially equal to one-eighth wavelength of the first resonant mode.
