Description

Technical Field

[0001] The utility model relates to the technical field of television antennas, in particular to a dual-polarization television antenna. Background Art

[0002] In existing technology, digital television signals are transmitted using both horizontal and vertical polarization to ensure signal stability and coverage. Therefore, television antennas are typically designed with oscillators capable of receiving both horizontally and vertically polarized signals. However, to achieve this dual-polarization reception, conventional antenna structures often utilize four independent antenna elements: two for horizontally polarized signals and two for vertically polarized signals.

[0003] This design requires four independent contacts. To output the signal, these four contacts must be matched and converted to output signals from two contacts in order to match the commonly used coaxial feeder system. This matching process typically requires additional circuitry and electronic components, which not only complicates the antenna's structural design but also reduces signal transmission efficiency. Furthermore, the addition of matching circuitry can lead to additional signal loss and unnecessary interference, compromising the strength and quality of signal reception.

[0004] Therefore, it is necessary to further improve and perfect the existing technology to overcome these shortcomings, and the present invention is made based on this situation. Utility Model Content

[0005] The utility model aims to overcome the deficiencies of the prior art and provide a dual-polarized television antenna which can simplify the antenna structure, reduce the complexity of the matching circuit, and improve the efficiency and quality of received signals.

[0006] The utility model is realized through the following technical solutions:

[0007] To solve the above technical problems, the present utility model provides a dual-polarized television antenna, comprising a first dipole group and a second dipole group, and a coaxial feeder, wherein the first dipole group comprises an integrally connected first vertical dipole and a first horizontal dipole, and a first feeding port provided at the connection between the two, and the second dipole group comprises an integrally connected second vertical dipole and a second horizontal dipole, and a second feeding port provided at the connection between the two, the first dipole group and the second dipole group are isolated from each other, and the two contacts of the coaxial feeder are respectively connected to the first feeding port and the second feeding port.

[0008] In order to further solve the technical problem to be solved by the present invention, the present invention provides a dual-polarized television antenna in which the first dipole group and the second dipole group are centrosymmetric.

[0009] In order to further solve the technical problem to be solved by the present invention, the present invention provides a dual-polarized television antenna, in which the first vertical oscillator, the first horizontal oscillator, the second vertical oscillator and the second horizontal oscillator are all closed rings or non-closed rings.

[0010] In order to further solve the technical problem to be solved by the present invention, in a dual-polarized television antenna provided by the present invention, the first vertical oscillator, the first horizontal oscillator, the second vertical oscillator, and the second horizontal oscillator are manufactured as follows:

[0011] a) Made of bent metal tubes; or

[0012] b) Made of metal printed circuits; or

[0013] c) Made of metal surface mount circuit;

[0014] The first vertical vibrator and the first horizontal vibrator share the same metal tube or the same printed circuit or the same metal surface mount circuit; the second vertical vibrator and the second horizontal vibrator share another metal tube or another printed circuit or another metal surface mount circuit.

[0015] Compared with the prior art, the utility model has the following advantages:

[0016] In this utility model, the first vertical oscillator and the first horizontal oscillator are integrally connected, and the second vertical oscillator and the second horizontal oscillator are also integrally connected. This means that each set of oscillators is equivalent to half a vertical oscillator and half a horizontal oscillator. This design not only offers structural simplicity but also enables simultaneous reception of horizontally and vertically polarized signals. Therefore, this antenna structure requires only two feed ports, enabling direct two-point output and avoiding complex signal matching processes, resulting in simplicity and efficiency.

[0020] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0021] This embodiment describes a dual-polarized television antenna, such as Figures 1 to 2As shown, the antenna includes a first dipole group 1 and a second dipole group 2, and a coaxial feed line 3. Specifically, the first dipole group 1 includes a first vertical dipole 11 and a first horizontal dipole 12 that are integrally connected, and a first feeding port 13 is provided at the connection between the two. Correspondingly, the second dipole group 2 includes a second vertical dipole 21 and a second horizontal dipole 22 that are integrally connected, and a second feeding port 23 is provided at the connection between the two. Of course, the first dipole group 1 and the second dipole group 2 are isolated from each other, and the two contacts of the coaxial feed line 3 are respectively connected to the first feeding port 13 and the second feeding port 23.

[0022] Furthermore, the first vibrator group 1 and the second vibrator group 2 are centrally symmetrical, and this design facilitates balanced reception and transmission of signals.

[0023] It's important to note that the first vertical oscillator 11 and the first horizontal oscillator 12 are integrally connected, as are the second vertical oscillator 21 and the second horizontal oscillator 22. This means each set of oscillators is equivalent to half a vertical oscillator and half a horizontal oscillator. This design not only offers structural simplicity but also enables simultaneous reception of both horizontally and vertically polarized signals. Therefore, the antenna structure requires only two feed ports, enabling direct two-point output and avoiding complex signal matching processes, resulting in simplicity and efficiency.

[0024] The utility model improves the efficiency and quality of received signals by simplifying the antenna structure and reducing the complexity of the matching circuit, thus bringing significant technical advantages.

[0025] To further expand the antenna's bandwidth, the first vertical oscillator 11, the first horizontal oscillator 12, the second vertical oscillator 21, and the second horizontal oscillator 22 can all be designed as closed rings or non-closed rings. This design helps improve the antenna's frequency response range, enabling it to better adapt to signal transmission requirements in different frequency bands.

[0026] From the perspective of manufacturing process, the first vertical vibrator 11, the first horizontal vibrator 12, the second vertical vibrator 21 and the second horizontal vibrator 22 are manufactured as follows:

[0027] a) Made of bent metal tubes (such as hollow aluminum tubes, copper tubes, iron tubes, etc.); or

[0028] b) Made of metal printed circuits (i.e. printed circuits on a circuit board); or

[0029] c) Made of metal surface mount circuits (i.e. metal circuits attached to a circuit board, such as aluminum foil surface mount);

[0030] The first vertical vibrator 11 and the first horizontal vibrator 12 share the same metal tube or the same printed circuit or the same metal surface mount circuit; the second vertical vibrator 21 and the second horizontal vibrator 22 share another metal tube or another printed circuit or another metal surface mount circuit.

[0031] This manufacturing process makes the antenna structure not only simple and easy to make, but also ensures good conductivity and durability.

[0032] In general, this embodiment provides a dual-polarized television antenna with a simple structure, convenient manufacturing, and high efficiency, which can effectively improve the efficiency and quality of received signals and has broad application prospects.
