ABSTRACT:
An indoor UHF antenna for a digital television includes a flat structure, which is easy to install and also can be adjusted to different receiving angles according to horizontal polarized waves or vertical polarized waves transmitted by different transmitters. The antenna device includes a circuit board, a main rod antenna, and an auxiliary rod antenna. The main rod antenna is horizontally welded with a signal feeder terminal of the circuit board, and the auxiliary rod antenna is parallel welded with an earth terminal of the circuit board for stabilizing signals. Thereby the whole antenna structure is flat and can be adjusted to any receiving angle easily, so as to match up and be suitable to receive wireless digital television signals of the horizontal polarized waves or vertical polarized waves from different transmitters.
