Description

Technical Field

[0001] This utility model relates to a television antenna. Background Technology

[0002] Currently, TV antennas on the market are large in size and complex in structure. Utility Model Content

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

[0004] This utility model discloses a butterfly-shaped TV antenna, comprising a PCB board, an insulating layer, and a copper layer disposed on the insulating layer. The copper layer includes two symmetrically arranged, butterfly-shaped receiving elements, with a gap between them. The gap gradually narrows from top to bottom, forming a horn-shaped structure. Each receiving element has a feed point on the inner side of its lower horn-shaped structure. The receiving element has a closed internal structure and an outer closed curve. The curve includes a first arc, a second arc, a third arc, and a diagonal line connected sequentially. The first and second arcs are located on the upper part of the receiving element, while the third arc and the diagonal line are located on the lower part. The first, second, third, and diagonal lines are connected by transition arcs. The feed point is located at the junction of the first and fourth arcs. The centers of the first and third arcs are on the side closer to the closed curve, while the center of the second arc is on the side farther from the closed curve. The angle between the two diagonal lines is 130-170 degrees. The butterfly-shaped TV antenna has an aesthetically pleasing structure and good signal reception.

[0005] The beneficial effects of this utility model are: the butterfly-shaped TV antenna has an aesthetically pleasing structure and good signal reception. Attached Figure Description

[0007] The markings in the diagram are: 1. Receiving oscillator, 2. Feed point, 11. First arc, 12. Second arc, 13. Third arc, 14. Diagonal line. Detailed Implementation

[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 butterfly-shaped 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 two symmetrically arranged, butterfly-shaped receiving elements 1. A gap is provided between the two receiving elements, and the gap gradually narrows from top to bottom into a horn-shaped structure. A feed point 2 is provided on the lower inner side of the horn-shaped structure of the receiving element 1. The inside of the receiving element 1 is a closed structure, and the outer ring is a closed curve. The curve includes a first arc 11, a second arc 12, and a third arc 13 connected in sequence. Line 13 and oblique line 14, the first arc 11 and the second arc 12 are located on the upper part of the receiving element 1, and the third arc 13 and oblique line 14 are located on the lower part of the receiving element 1. The first arc 11, the second arc 12, the third arc 13 and the oblique line 14 are connected by a transition arc. The feed point 2 is set at the connection between the first arc 11 and the fourth arc 14. The center of the first arc 11 and the third arc 13 is on the side closer to the closed curve, and the center of the second arc 12 is on the side farther from the closed curve. The angle between the two oblique lines 14 is 130~170 degrees. The butterfly-shaped TV antenna has an aesthetically pleasing structure and good signal reception.
