Description

Technical Field

[0001] This solution belongs to the field of television antenna technology, specifically involving a dual-polarized flat-panel TV antenna. Background Technology

[0002] With the leapfrog development of television technology from analog to digital signals, users' demands for visual experience have upgraded from simply "having a signal" to higher-level needs such as high-definition picture quality, real-time interaction, and multi-scene coverage. Requirements for picture clarity, signal stability, and device aesthetics continue to rise. Against this backdrop, television signal reception technology has become a crucial factor affecting user experience. As the core component of signal reception, the development of television antenna technology directly determines the overall performance of the television system.

[0003] Traditional rod antennas are designed based on the principles of dipoles or Yagi antennas, matching the physical length of a metal element to a specific frequency band. In the VHF (30-300MHz) band, this requires an element structure 1-2 meters long, resulting in a bulky size and limited installation. Planar antennas, employing microstrip patch or slot antenna structures, transmit and receive electromagnetic waves through metal radiating elements on a dielectric substrate. Their thickness can be controlled to within 5mm, meeting the integration requirements of modern electronic devices. Due to their lightweight, thin, and integrated characteristics, planar antennas have become a research hotspot.

[0004] Different countries and regions allocate television signals to the VHF and UHF bands according to their spectrum allocation policies. For example, in China's Digital Terrestrial Television (DTMB) standard, both the VHF and UHF bands are used. Therefore, modern digital television requires antennas to simultaneously cover both the VHF (174-230MHz) and UHF (470-860MHz) bands to ensure reception of all available television channels and avoid the inability to receive some channels due to band limitations. Digital television signals are also transmitted using both horizontal and vertical polarization, requiring antennas to be able to receive both polarizations simultaneously in the UHF and VHF bands to avoid signal loss. Currently, there are flat-panel TV antennas that can stably receive both horizontal and vertical polarization signals simultaneously in the UHF and VHF bands, but their size is typically 320×320mm. 2 The above makes it difficult to overcome size limitations while maintaining existing receiving performance. Utility Model Content

[0005] This solution aims to overcome at least one deficiency in the prior art and provide a dual-polarized flat-panel TV antenna that can simultaneously achieve stable reception of horizontally and vertically polarized signals in both the UHF and VHF bands while reducing the size of the antenna.

[0006] To solve the above-mentioned technical problems, the following technical solution is adopted:

[0007] A dual-polarized flat-panel TV antenna includes a horizontally polarized dipole assembly, a vertically polarized dipole assembly, and a ground terminal. All three assemblies are sheet-like structures laid on a plane. The horizontally polarized dipole assemblies are arranged at a distance from each other on a first side of the ground terminal, and the vertically polarized dipole assemblies are arranged at a distance from each other on a second side of the ground terminal. The ground terminal, together with the horizontally and vertically polarized dipole assemblies, forms a fully matched polarized antenna. The horizontally polarized dipole assembly includes a UHF horizontally polarized dipole and a VHF horizontally polarized dipole, with the VHF horizontally polarized dipole arranged at a distance from each other on a second side of the UHF horizontally polarized dipole. Both the UHF and VHF horizontally polarized dipoles are arranged horizontally, each having a first end away from the ground terminal and a second end close to the ground terminal. The second end of the VHF horizontally polarized dipole is connected to the second end of the UHF horizontally polarized dipole, and the second end of the UHF horizontally polarized dipole constitutes a first feed terminal. The vertically polarized oscillator assembly includes a UHF vertically polarized oscillator and a VHF vertically polarized oscillator, with the VHF vertically polarized oscillator arranged on a first side of the UHF vertically polarized oscillator. Both the UHF and VHF vertically polarized oscillators are arranged vertically, and each has a first end away from the grounding terminal and a second end close to the grounding terminal. The second end of the VHF vertically polarized oscillator is connected to the second end of the UHF vertically polarized oscillator, and the second end of the UHF vertically polarized oscillator constitutes a second feed terminal. The first side is the vertical side, and the second side is the horizontal side.

[0008] This design integrates the horizontally polarized vibrator assembly, the vertically polarized vibrator assembly, and the grounding terminal in a coplanar asymmetric manner, significantly reducing the antenna's physical size. Whether horizontally or vertically, the antenna's physical size is below 250mm, and its area is reduced by more than 20% compared to existing similar antennas. Furthermore, the antenna utilizes the vibrator connection method and grounding terminal matching to allow for a design size of 250×250mm. 2 It covers the UHF band (470–860 MHz) and the VHF band (174–230 MHz) within the area, and achieves stable reception of horizontally polarized and vertically polarized signals in both the UHF and VHF bands. While reducing the physical size, it does not sacrifice the dual-band dual-polarization reception capability.

[0009] The UHF horizontally polarized vibrator is preferably configured in a funnel shape, with the opening of the funnel away from the grounding terminal and the neck of the funnel close to the grounding terminal. This reduces the physical size of the UHF horizontally polarized vibrator, thereby further reducing the physical size of the antenna. Simultaneously, it ensures that the dual-band dual-polarized signal reception performance of the antenna is not affected, and may even be improved. Similarly, the UHF vertically polarized vibrator is also preferably configured in a funnel shape, with the opening of the funnel away from the grounding terminal and the neck of the funnel close to the grounding terminal. This reduces the physical size of the UHF vertically polarized vibrator, thereby further reducing the physical size of the antenna. Simultaneously, it ensures that the dual-band dual-polarized signal reception performance of the antenna is not affected, and may even be improved.

[0010] The funnel-shaped structure preferably comprises a first part, a second part, and a third part. The first, second, and third parts of the UHF horizontally polarized vibrator are connected sequentially in the horizontal direction, and the first, second, and third parts of the UHF vertically polarized vibrator are connected sequentially in the vertical direction. The first part is far from the grounding terminal, and the third part is close to the grounding terminal. The first part is rectangular, the second part is an isosceles trapezoid, and the third part is L-shaped. The lower base of the second part is the same width as one side of the first part and is connected to it, and the upper base of the second part is the same width as one end of the third part and is connected to it. This is to further reduce the physical size of the UHF horizontally polarized vibrator and the UHF vertically polarized vibrator while ensuring that the dual-band dual-polarized signal reception performance of the antenna does not decrease but increases, thereby further reducing the physical size of the antenna.

[0011] The third part can be divided into a first segment and a second segment. The free end of the first segment is the same width as and connected to the upper base of the second part. The free end of the second segment of the UHF horizontally polarized oscillator is located on the second side of its first segment to connect to the VHF horizontally polarized oscillator; the free end of the second segment of the UHF vertically polarized oscillator is located on the first side of its first segment to connect to the VHF vertically polarized oscillator. The second segment of the UHF horizontally polarized oscillator constitutes the first feed terminal, and the second segment of the UHF vertically polarized oscillator constitutes the second feed terminal. Both segments have a length of 40±2mm and a width of 10±0.5mm, serving both as a matching network and participating in low-frequency radiation, which is beneficial for achieving a synergistic breakthrough in miniaturization and dual-band dual-polarization performance.

[0012] The VHF horizontally polarized dipole is preferably configured with a serpentine structure, and the VHF vertically polarized dipole is also preferably configured with a serpentine structure, which is beneficial for achieving the required dipole length within a limited space. The serpentine structure preferably includes a first segment, a second segment, and a third segment, which are connected sequentially. The first segment is furthest from the grounding terminal, and the third segment is close to the grounding terminal. The first segment includes a straight segment, the second segment is a zigzag segment with a square waveform, and the third segment is a straight segment. This special structure maximizes the equivalent electrical length within a limited space. The first segment acts as the main radiator, the second segment compresses its physical size through dense bending, and the third segment serves as a matching segment connecting the feed point. This achieves miniaturization while ensuring the stability of the radiation pattern, meeting the spatial coverage requirements for indoor reception. The first segment of the VHF horizontally polarized dipole includes two straight segments and one curved segment, with the curved segment sandwiched between the two straight segments, forming an Ω shape. This streamlined layout allows the antenna to naturally bypass the mounting hole without affecting the radiation characteristics.

[0013] Specifically, the horizontal dimension of the antenna can be reduced to 220-250mm, and the vertical dimension can also be reduced to 220-250mm.

[0014] The antenna can also be configured with a support plate, on which the horizontally polarized vibrator assembly, the vertically polarized vibrator assembly, and the grounding terminal are all laid.

[0015] Compared with existing technologies, this solution offers the following advantages: This solution integrates the horizontally polarized vibrator assembly, the vertically polarized vibrator assembly, and the grounding terminal in a coplanar asymmetric manner, significantly reducing the physical size of the antenna. Whether in the horizontal or vertical direction, the antenna's physical size is below 250mm, and the antenna area is reduced by more than 20% compared to existing similar antennas. Furthermore, by utilizing the vibrator connection method and the matching of the grounding terminal, the antenna can be designed to be 250×250mm in size. 2 It covers the UHF band (470–860 MHz) and the VHF band (174–230 MHz) within the area, and achieves stable reception of horizontally polarized and vertically polarized signals in both the UHF and VHF bands. While reducing the physical size, it does not sacrifice the dual-band dual-polarization reception capability. Attached Figure Description

[0021] Explanation of reference numerals in the attached drawings: Horizontal polarization oscillator assembly 100, UHF horizontal polarization oscillator 110, VHF horizontal polarization oscillator 120, Vertical polarization oscillator assembly 200, UHF vertical polarization oscillator 210, VHF vertical polarization oscillator 220, First part 111, 211, Second part 112, 212, Third part 113, 213, First line segment 121, 221, Second line segment 122, 222, Third line segment 123, 223, Grounding terminal 300, Support plate 400. Detailed Implementation

[0022] To enable those skilled in the art to better understand this solution, the following detailed description is provided in conjunction with specific embodiments.

[0023] Figure 1 A possible dual-polarized flat-panel TV antenna is illustrated. The antenna includes a horizontally polarized dipole assembly 100, a vertically polarized dipole assembly 200, and a ground terminal 300. The horizontally polarized dipole assembly 100 includes a UHF horizontally polarized dipole 110 and a VHF horizontally polarized dipole 120, and the vertically polarized dipole assembly 200 includes a UHF vertically polarized dipole 210 and a VHF vertically polarized dipole 220. The ground terminal 300 serves as a common ground terminal and, together with the horizontally polarized dipole assembly 100 (including the UHF horizontally polarized dipole 110 and the VHF horizontally polarized dipole 120), forms a fully matched horizontally polarized antenna for receiving horizontally polarized signals in the UHF and VHF bands. It also, together with the vertically polarized dipole assembly 200 (including the UHF vertically polarized dipole 210 and the VHF vertically polarized dipole 220), forms a fully matched vertically polarized antenna for receiving vertically polarized signals in the UHF and VHF bands.

[0024] The horizontally polarized vibrator assembly 100, the vertically polarized vibrator assembly 200, and the grounding terminal 300 are all sheet-like structures, laid out on a flat surface. All three are made of conductive materials, specifically conductive ink (printed with metallic ink), fiberglass boards, or metals such as aluminum, copper, and iron. The surface supporting them can be the surface of a support plate 400 (e.g., a PC sheet), or the surface of a glass window, wooden wall, or non-metallic bracket. If the horizontally polarized vibrator assembly 100, the vertically polarized vibrator assembly 200, and the grounding terminal 300 are made of conductive ink, they can be directly printed on the surface of the support plate 400 (e.g., a PC sheet), in which case the antenna also includes the support plate 400. If the horizontally polarized oscillator assembly 100, the vertically polarized oscillator assembly 200, and the grounding terminal 300 are made of metal materials such as aluminum, copper, and iron, then the horizontally polarized oscillator assembly 100, the vertically polarized oscillator assembly 200, and the grounding terminal 300 can be attached by the user to the surface of glass windows, wooden walls, non-metallic brackets, etc. in the place of use.

[0025] For ease of description, a Cartesian coordinate system can be established in the plane supporting the horizontally polarized oscillator assembly 100, the vertically polarized oscillator assembly 200, and the grounding terminal 300, with the horizontal direction as the X-axis and the vertical direction as the Y-axis. In this coordinate system, one side of the Y-axis (i.e., the left or right side) can be defined as the first side, and one side of the X-axis (i.e., the upper or lower side) can be defined as the second side. In other words, the first side is the vertical side, and the second side is the horizontal side. The horizontally polarized dipole assembly 100 (including UHF horizontally polarized dipole 110 and VHF horizontally polarized dipole 120) is arranged at a distance on the first side of the ground terminal 300, the VHF horizontally polarized dipole 120 is arranged at a distance on the second side of the UHF horizontally polarized dipole 110, the vertically polarized dipole assembly 200 (including UHF vertically polarized dipole 210 and VHF vertically polarized dipole 220) is arranged at a distance on the second side of the ground terminal 300, and the VHF vertically polarized dipole 220 is arranged at a distance on the first side of the UHF vertically polarized dipole 210. This integrates the horizontally polarized dipole assembly 100, the vertically polarized dipole assembly 200, and the ground terminal 300 in a coplanar asymmetric manner to reduce the physical size of the antenna.

[0026] UHF horizontally polarized oscillator 110, VHF horizontally polarized oscillator 120, UHF vertically polarized oscillator 210, and VHF vertically polarized oscillator 220 can be collectively referred to as oscillators. UHF horizontally polarized oscillator 110 and VHF horizontally polarized oscillator 120 are arranged horizontally, while UHF vertically polarized oscillator 210 and VHF vertically polarized oscillator 220 are arranged vertically. Each oscillator has a first end and a second end, with the first end located away from the grounding terminal 300 and the second end located close to the grounding terminal 300. The second end of VHF horizontally polarized oscillator 120 is connected to the second end of UHF horizontally polarized oscillator 110, forming a dual-band combined oscillator for receiving horizontally polarized signals. The second end of UHF horizontally polarized oscillator 110 constitutes a first feed terminal, serving as the common feed terminal for both UHF horizontally polarized oscillator 110 and VHF horizontally polarized oscillator 120. The second end of the VHF vertical polarization vibrator 220 is connected to the second end of the UHF vertical polarization vibrator 210, forming a dual-band combined vibrator for receiving vertical polarization signals. The second end of the UHF vertical polarization vibrator 210 constitutes a second feed terminal, serving as a common feed terminal for the UHF vertical polarization vibrator 210 and the VHF vertical polarization vibrator 220. The first and second feed terminals can be electrically connected to a mixer, which mixes the horizontal and vertical polarization signals before outputting them to the television set via a coaxial cable.

[0027] The aforementioned antenna integrates the horizontally polarized dipole assembly 100, the vertically polarized dipole assembly 200, and the grounding terminal 300 in a coplanar asymmetric manner, significantly reducing the antenna's physical size. Whether in the horizontal or vertical direction, the antenna's physical size is less than 250mm, and the antenna area is reduced by more than 20% compared to existing similar antennas. Furthermore, by utilizing the dipole connection method and the matching of the grounding terminal 300, the antenna can be designed to be 250×250mm in size. 2 It covers the UHF band (470–860 MHz) and the VHF band (174–230 MHz) within the area, and achieves stable reception of horizontally polarized and vertically polarized signals in both the UHF and VHF bands. While reducing the physical size, it does not sacrifice the dual-band dual-polarization reception capability.

[0028] Both the UHF horizontally polarized dipole 110 and the UHF vertically polarized dipole 210 can be configured as a funnel-shaped structure to reduce their physical size, thereby further reducing the physical size of the antenna. Simultaneously, this ensures that the dual-band dual-polarization signal reception performance of the antenna is not affected, and may even be improved. Specifically, the funnel-shaped structure has its opening far from the grounding terminal 300, and its neck close to the grounding terminal 300.

[0029] The funnel-shaped structure can be configured with a first part, a second part, and a third part. The first part 111, the second part 112, and the third part 113 of the UHF horizontally polarized vibrator 110 are connected sequentially in the horizontal direction, and the first part 211, the second part 212, and the third part 213 of the UHF vertically polarized vibrator 210 are connected sequentially in the vertical direction. The first part is away from the grounding terminal 300, and the third part is close to the grounding terminal 300. The first part is rectangular, the second part is an isosceles trapezoid, and the third part is L-shaped. The lower base of the second part is the same width as one side of the first part and is connected, and the upper base of the second part is the same width as one end of the third part and is connected. This is to further reduce the physical size of the UHF horizontally polarized vibrator 110 and the UHF vertically polarized vibrator 210 while ensuring that the dual-band dual-polarized signal reception performance of the antenna does not decrease but increases, thereby further reducing the physical size of the antenna.

[0030] The third part can be divided into a first segment and a second segment. The free end of the first segment is connected to the trapezoidal upper base of the second segment with the same width. The second segment extends in a specific direction as an independent feed terminal. The free end of the second segment of the UHF horizontally polarized oscillator 110 is located on the second side of its first segment to connect to the VHF horizontally polarized oscillator 120. The free end of the second segment of the UHF vertically polarized oscillator 210 is located on the first side of its first segment to connect to the VHF vertically polarized oscillator 220. The second segment of the UHF horizontally polarized oscillator 110 constitutes the first feed terminal, and the second segment of the UHF vertically polarized oscillator 210 constitutes the second feed terminal. Both segments have a length of 40±2mm and a width of 10±0.5mm, which both match the network and participate in low-frequency radiation, thus facilitating a synergistic breakthrough in miniaturization and dual-band dual-polarization performance.

[0031] Both the VHF horizontally polarized oscillator 120 and the VHF vertically polarized oscillator 220 can be configured with a serpentine structure. The meandering path facilitates achieving the required oscillator length within a limited space. The serpentine structure can be configured with a first segment, a second segment, and a third segment, connected sequentially. The first segment is furthest from the grounding terminal 300, and the third segment is closest to it. The first segment includes a straight section, the second segment is a zigzag segment with a square waveform, and the third segment is a straight section. This special structure maximizes the equivalent electrical length within a limited space. The first segment acts as the main radiator, the second segment compresses its physical size through dense bending, and the third segment serves as a matching segment connecting the feed point. This achieves miniaturization while ensuring the stability of the radiation pattern, meeting the spatial coverage requirements for indoor reception. In the design of the VHF horizontally polarized oscillator 120, the first segment 121 can adopt a unique Ω-shaped structure, consisting of two straight segments and an arc segment connecting them in the middle. This streamlined layout allows the antenna to naturally bypass the mounting hole position without affecting the radiation characteristics.

[0032] Specifically, the horizontal dimension of this antenna can be reduced to 220-250mm, and the vertical dimension can also be reduced to 220-250mm. Figure 1 Taking the antenna shown as an example, its physical dimensions are 220mm (horizontal) × 250mm (vertical). Specifically, the UHF horizontally polarized element 110 has a horizontal dimension of 141±2mm and a vertical dimension of 65±2mm; the UHF vertically polarized element 210 has a vertical dimension of 141±2mm and a horizontal dimension of 65±2mm; and the VHF horizontally polarized element 120 and the VHF vertically polarized element 220 have a length of 87±2cm and a width of 2±0.5mm. Figure 1 The radiation pattern, gain, and VSWR of the antenna shown are as follows: Figures 2-4 As shown, stable reception of dual-polarized signals in both UHF and VHF bands was successfully achieved within a compact rectangular space with sides of 220–250 mm, perfectly meeting the concealed installation requirements of modern ultra-thin televisions. With an element length of 87±2 cm, the VHF horizontally polarized element 120 and the VHF vertically polarized element 220 can receive signals not only in the VHF band but also in the FM band.

Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this solution should be included within the scope of protection of the claims of this solution.
