Abstract:
1. An antenna for receiving digital television signals, comprising: a substrate; a radiating plate formed on the substrate, the radiating plate having a first radiating area, a second radiating area and a slit formed between the first radiating area and the second radiating area, wherein the first radiating area includes a first feed point and a first connection point, the second radiating area includes a second connection point and a second feed point corresponding to the first feed point, the slit includes at least one bent portion and extends between the first radiating area and the second radiating area; a first radiating element pivotedly connected to the first connection point so that the first radiating element is capable of being rotated relative to the radiating plate; and a second radiating element pivotedly connected to the second connection point so that the second radiating element is capable of being rotated relative to the radiating plate, wherein the first radiating element and the second radiating element are constructed as a dipole antenna structure of the antenna so as to excite a first resonant mode; wherein the radiating plate acts as a matching circuit thereon so as to excite a second resonant mode, a center frequency of the second resonant mode is shifted toward a center frequency of the first resonant mode so that the antenna has a wideband characteristic.
