Description

Technical Field

[0001] The present invention relates to the technical field of television antennas, and in particular to a dual-polarized television antenna. Background Art

[0002] In the prior art, digital TV signals are transmitted in two ways: horizontal polarization and vertical polarization to ensure signal stability and coverage. Therefore, TV antennas are usually designed to be able to receive both horizontally polarized signals and vertically polarized signals. However, in order to achieve the reception of such dual-polarized signals, traditional antenna structures often use four independent antenna units, including two oscillators for horizontally polarized signals and two oscillators for vertically polarized signals.

[0003] This design requires four independent contacts, and when outputting signals, in order to match the commonly used coaxial feeder system, the signals of these four contacts must be matched and converted into signal outputs of two contacts. This matching process usually requires additional circuits and electronic components, which not only makes the structural design of the antenna more complicated, but also reduces the signal transmission efficiency to a certain extent. In addition, the addition of matching circuits may bring additional signal loss and unnecessary interference, affecting the strength and quality of signal reception.

[0004] Therefore, it is necessary to further improve and perfect the prior art to overcome these shortcomings, and the present invention is made based on this situation. Summary of the invention

[0005] The object of the present invention is to overcome the deficiencies of the prior art and to 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 the received signal.

[0006] The present invention is achieved through the following technical solutions:

[0007] In order to solve the above technical problems, the present invention 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 a first vertical dipole and a first horizontal dipole connected in an integral manner, and a first feeding port arranged at the connection between the two, the second dipole group comprises a second vertical dipole and a second horizontal dipole connected in an integral manner, and a second feeding port arranged 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, in a dual-polarized television antenna provided by the present invention, the first dipole group and the second dipole group are centrally symmetrical.

[0009] 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 vibrator, the first horizontal vibrator, the second vertical vibrator and the second horizontal vibrator 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 vibrator, the first horizontal vibrator, the second vertical vibrator and the second horizontal vibrator are manufactured as follows:

[0011] a) Made of bent metal tube; 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 mounted circuit; the second vertical vibrator and the second horizontal vibrator share another metal tube or another printed circuit or another metal surface mounted circuit.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] In the present invention, the first vertical vibrator and the first horizontal vibrator are connected in an integrated manner, and the second vertical vibrator and the second horizontal vibrator are also connected in an integrated manner, which means that each group of vibrators is equivalent to being composed of half of the vertical vibrators and half of the horizontal vibrators. Such a design is not only structurally simple, but also capable of simultaneously receiving horizontally polarized signals and vertically polarized signals. Therefore, the antenna structure only requires two feeding ports, can achieve direct two-point output, avoids the complex signal matching process, and is simple and efficient.

[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 in conjunction with the accompanying drawings and specific implementation methods.

[0021] This embodiment describes a dual-polarized television antenna, such as Figure 1 to Figure 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 an integrally connected first vertical dipole 11 and a first horizontal dipole 12, and a first feeding port 13 is provided at the connection between the two. Correspondingly, the second dipole group 2 includes an integrally connected second vertical dipole 21 and a second horizontal dipole 22, 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 is conducive to balanced reception and transmission of signals.

[0023] It should be noted that the first vertical vibrator 11 and the first horizontal vibrator 12 are connected in an integrated manner, and the second vertical vibrator 21 and the second horizontal vibrator 22 are also connected in an integrated manner, which means that each group of vibrators is equivalent to half of the vertical vibrator and half of the horizontal vibrator. Such a design is not only structurally simple, but also can receive horizontally polarized signals and vertically polarized signals at the same time. Therefore, the antenna structure only requires two feeding ports, can achieve direct two-point output, avoids the complex signal matching process, and is simple and efficient.

[0024] The present invention 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] In order to further expand the bandwidth of the antenna, the first vertical oscillator 11, the first horizontal oscillator 12, the second vertical oscillator 21 and the second horizontal oscillator 22 can be designed as a closed ring or a non-closed ring. This design helps to improve the frequency response range of the antenna, so that it can better adapt to the signal transmission requirements of 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 circuit boards, such as aluminum foil surface mount, etc.);

[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; 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.
