Description

Technical Field

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

[0002] UHF TV antennas are large and have poor reception. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a small-sized UHF antenna with excellent reception.

[0004] This utility model discloses a dipole UHF antenna with a silver paste coating process, comprising a matching element and a dipole element disposed below the matching element. There are two dipole elements symmetrically distributed on both sides of the matching element. The matching element is rectangular and has two non-connected first matching gaps symmetrically arranged along its length. The matching element is hollow and has a rectangular upper part and a trapezoidal lower part that is wider at the top and narrower at the bottom. The matching element has a feed point at the upper part near the other matching element. There is a second matching gap between the two dipole elements and a third matching gap between the dipole elements and the matching element. The combination of dipole and matching dipole enables broadband reception of terrestrial television signals; the first matching slot, the second matching slot, and the third matching slot form broadband impedance matching; the television signal is received by the matching dipole and the dipole, and then output through the feed point; due to the small size of the designed antenna but the utilization of induced radio waves, as well as the relatively large area of ​​the metal sheet and the broadband matching with multiple slots, a small-volume, high-gain broadband television signal reception is achieved, which has the beneficial effect of reducing packaging and transportation costs.

[0005] Preferably, the right end of the left dipole is flush with the right end of the first matching gap on the left, and the left end of the right dipole is flush with the left end of the first matching gap on the right. This results in good reception and ease of use.

[0006] Preferably, the first matching gap width is 1~3mm. The second matching gap width is 2~5mm. The third matching gap width is 1~3mm. This provides good matching effect and strong anti-interference capability.

[0007] The beneficial effects of this invention are as follows: the combination of dipole and matching elements enables broadband reception of terrestrial television signals; the first matching slot, the second matching slot, and the third matching slot form broadband impedance matching; the television signal is received by the matching element and the dipole, and then output through the feed point; due to the small size of the designed antenna but the utilization of induced electromagnetic waves, as well as the relatively large area of ​​the metal sheet and the broadband matching with multiple slots, a small-volume, high-gain broadband television signal reception is achieved, reducing packaging and transportation costs.

[0010] 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.

[0011] like Figure 1 As shown, a UHF antenna with a silver paste coating process includes a matching element 1 and two dipole elements 4 disposed at the lower part of the matching element 1. The two dipole elements 4 are symmetrically distributed on both sides of the matching element 1. The matching element 1 is rectangular and has two non-connected first matching gaps 2 symmetrically arranged along its length. The matching element 1 is hollow and has a rectangular upper part and a trapezoidal lower part that is wider at the top and narrower at the bottom. The matching element 1 has a feed point at the upper part near the other matching element 1. A second matching gap 3 is provided between the two dipole elements 4, and a third matching gap 5 is provided between the dipole elements 4 and the matching element 1. The right end of the left dipole element 4 is flush with the right end of the left first matching gap 2, and the left end of the right dipole element 4 is flush with the left end of the right first matching gap 2. The width of the first matching gap 2 is 1~3mm, the width of the second matching gap 3 is 2~5mm, and the width of the third matching gap 5 is 1~3mm. The combination of dipole and matching dipole enables broadband reception of terrestrial television signals; the first matching slot, the second matching slot, and the third matching slot form broadband impedance matching; the television signal is received by the matching dipole and the dipole, and then output through the feed point; due to the small size of the designed antenna but the utilization of induced radio waves, as well as the relatively large area of ​​the metal sheet and the broadband matching with multiple slots, a small-volume, high-gain broadband television signal reception is achieved, which has the beneficial effect of reducing packaging and transportation costs.
