An indoor UHF antenna device for a digital television includes a flat structural design. The flat indoor UHF antenna device includes a circuit board having a wireless signal processing circuit and an antenna. A metal wire bent as a long rectangular antenna and having a gap forms the antenna. Two signal feeder points are defined at two locations having a same distance from two long sides of the long rectangular antenna respectively, and thereby the antenna includes a first antenna part having a gap and a second antenna part for impedance matching. The antenna is set horizontally on the circuit board with the signal feeder points welded on the circuit board. Thereby the antenna device of the present invention is enhanced to receive wireless signals of polarized waves transmitted by different transmitters.

What is claimed is: 1. A flat indoor UHF antenna device for a digital television comprising: a circuit board mainly comprising a wireless signal processing circuit and a connector for connecting with a coaxial cable; an antenna which is formed by a metal wire formed as a long rectangular antenna having a gap, wherein two signal feeder points are defined at two locations having a same distance from two long sides of the long rectangular antenna respectively, and thereby the antenna comprising a first antenna part having a gap and a second antenna part for impedance matching, and wherein the antenna is set horizontally on the circuit board with the signal feeder points welded on the circuit board. 2. The flat indoor UHF antenna device for the digital television as defined in claim 1, wherein the digital television signal processing circuit comprises: a signal wave filter with an input terminal connecting to a signal feeder terminal of the long rectangular antenna for capturing a wireless signal of a specific frequency band; a high anti-noise amplifier connected to an output terminal of the signal wave filter for filtering the noise of the wireless signal and then amplifying the signal and output; a wave-filter and power supply circuit wherein an input terminal is connected to an output terminal of the high anti-noise amplifier, so as to filter the amplified wireless signal again, and to capture a digital television signal of a UHF frequency band, wherein an output terminal is connected to the TV connector of the circuit, wherein when the TV connector is connected to a television via the coaxial cable, a D.C. power supply to the connector begins, and further the wave-filter and power supply circuit comprises an inductance and a capacitance, thereby when the output terminal of the wave-filter and power supply circuit is connected to the TV connector, the D.C. power is supplied to the high anti-noise amplifier via the capacitance; and a power regulation circuit wherein an input terminal is connected to a D.C. power supply, wherein the input D.C. power supply is outputted to the high anti-noise amplifier via a constant voltage regulator. 3. The flat indoor UHF antenna device for the digital television as defined in claim 2, wherein the flat indoor UHF antenna device is placed inside a casing, wherein the casing comprises: a base comprising a U-shaped cross-section for receiving the circuit board and the long rectangular antenna; a lid for covering an opening of the base, and also for covering the circuit board and the long rectangular antenna; and a plate for covering the lid and also reinforcing the base. 4. The flat indoor UHF antenna device for the digital television as defined in claim 3, wherein a plurality of upward mounts are configured at a bottom of the base for supporting the long rectangular antenna. 5. The flat indoor UHF antenna device for the digital television as defined in claim 4, wherein a downward sunken ladder is formed at an inner part of a side upper face of the base, and wherein a plurality of integrated troughs are formed on the ladder, wherein a plurality of integrated feet are formed on an underside of the lid corresponding to the integrated troughs on the side of the base, so that the lid can be integrated with the ladder of the base. 6. The flat indoor UHF antenna device for the digital television as defined in claim 3, wherein a back of the base is configured with a bearing leg. 7. The flat indoor UHF antenna device for the digital television as defined in claim 1, wherein the flat indoor UHF antenna device is placed inside a casing, wherein the casing comprises: a base comprising a U-shaped cross-section for receiving the circuit board and the long rectangular antenna; a lid for covering an opening of the base, and also for covering the circuit board and the long rectangular antenna; and a plate covering the lid and reinforcing the base. 8. The flat indoor UHF antenna device for the digital television as defined in claim 7, wherein a plurality of upward mounts are configured at a bottom of the base for supporting the long rectangular antenna. 9. The flat indoor UHF antenna device for the digital television as defined in claim 8, wherein a downward sunken ladder is formed at an inner part of a side upper face of the base, and wherein a plurality of integrated troughs are formed on the ladder, wherein a plurality of integrated feet are formed on an underside of the lid corresponding to the integrated troughs on the side of the base, so that the lid can be integrated with the ladder of the base. 10. The flat indoor UHF antenna device for the digital television as defined in claim 7, wherein a back of the base is configured with a bearing leg.
