Description

Technical Field

[0001] This utility model relates to the field of signal processing, and in particular to a digital television antenna. Background Technology

[0002] Terrestrial digital television transmission and reception methods use a single-transmit, single-receive processing approach to achieve digital television reception. However, due to the narrow passband and low efficiency of single-channel transmission, high-pixel, high-speed image transmission cannot be achieved. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a compact, thin-film television antenna.

[0004] This utility model discloses a novel television antenna, comprising a PCB board. The PCB board includes an insulating layer and a copper layer disposed on the insulating layer. The copper layer includes a first vibrator, a second vibrator, and a common vibrator ground plane. The common vibrator ground plane is L-shaped and located at the upper right corner, including a horizontal section and a vertical section. The first and second vibrator bodies are elliptical. The bottom of the first vibrator has a first L-shaped matching line. The middle of the second vibrator has a second L-shaped matching line passing through its short axis. The top of the first vibrator has a first feed point, and the right side of the second vibrator has a second feed point. The common vibrator ground plane has a third feed point at the position corresponding to the first feed point and a fourth feed point at the position corresponding to the second feed point. The first and second vibrator bodies are disposed inside the common vibrator ground plane, with the first vibrator body disposed to the left of the second vibrator body. The long axis of the first vibrator body is perpendicular to the horizontal section of the ground plane, and the long axis of the second vibrator body is perpendicular to the vertical section of the ground plane. The first dipole element, the first L-shaped matching line, the first feed point, the third feed point, and the common dipole ground plane constitute a horizontal signal receiving unit. The second dipole element, the second L-shaped matching line, the second feed point, the fourth feed point, and the common dipole ground plane constitute a vertical signal receiving unit. The horizontal and vertical signal receiving units are combined to form a receiving dipole. The insulating layer is made of FR (Flat Metal). The horizontal signal receiving unit is used to receive horizontally radiated signals, and the vertical signal receiving unit is used to receive vertically radiated signals. The horizontally radiated signals are received by the first dipole element of the horizontal signal receiving unit and output from the first and third feed points. The vertically radiated signals are received by the second dipole element of the vertical signal receiving unit and output from the second and fourth feed points. The use of the same common ground plane by the horizontal and vertical signal receiving units reduces the relative volume of the entire antenna by about half, achieving a small and thin design. The 2*2 combination of the horizontal and vertical signal receiving units enables signal reception of ATSC TV3.0 2*2 MOMI technology.

[0005] The beneficial effects of this utility model are: the use of the same common grounding ground for the horizontal signal receiving unit and the vertical signal receiving unit reduces the relative volume of the entire antenna by about half, achieving a small and thin size; the 2*2 combination of the horizontal signal receiving unit and the vertical signal receiving unit enables signal reception of ATSC TV3.0 2*2 MOMI technology.

[0008] The present invention will now be described in further detail with reference to the accompanying drawings, but it should not be construed as limiting the scope of the subject matter of the present invention to the above embodiments.

[0009] like Figure 1As shown, a novel television antenna includes a PCB board. The PCB board includes an insulating layer and a copper layer disposed on the insulating layer. The copper layer includes a first vibrator 1, a second vibrator 2, and a common ground plane 3. The common ground plane 3 is L-shaped and located at the upper right corner, including a horizontal section and a vertical section. The first vibrator 1 and the second vibrator 2 are elliptical in shape. The bottom of the first vibrator 1 is provided with a first L-shaped matching line 12. The middle of the second vibrator 2 is provided with a second L-shaped matching line 22 passing through the short axis of its body. A first feed point 11 is located at the top of a transducer 1, and a second feed point 21 is located on the right side of a second transducer 2. A common transducer floor 3 has a third feed point 31 corresponding to the first feed point 11 and a fourth feed point 32 corresponding to the second feed point 21. The first transducer 1 and the second transducer 2 are located inside the common transducer floor 3, with the first transducer 1 located to the left of the second transducer 2. The long axis of the first transducer 1 is perpendicular to the horizontal section of the floor, and the long axis of the second transducer 2 is perpendicular to the vertical section of the floor. The first transducer 1, the first L-shaped matching line 12, the first feed point 11, the third feed point 31, and the common transducer floor 3 form a horizontal signal receiving unit. The second transducer 2, the second L-shaped matching line 22, the second feed point 21, the fourth feed point 32, and the common transducer floor 3 form a vertical signal receiving unit. The horizontal and vertical signal receiving units are combined to form a receiving transducer. The insulating layer is made of FR4. The horizontal signal receiving unit is used to receive horizontally radiated signals, and the vertical signal receiving unit is used to receive vertically radiated signals. The horizontally radiated signals are received by the first dipole element 1 of the horizontal signal receiving unit and output from the first feed point 11 and the third feed point 31. The vertically radiated signals are received by the second dipole element 2 of the vertical signal receiving unit and output from the second feed point 21 and the fourth feed point 32. The horizontal and vertical signal receiving units use the same common ground plane 3, which reduces the relative volume of the entire antenna by about half, achieving a small and thin design. The 2*2 combination of the horizontal and vertical signal receiving units enables signal reception of ATSC TV3.0 2*2 MOMI technology.
