[0001] The utility model belongs to the technical field of antenna arrays, and more specifically, particularly relates to a high- and low-frequency digital television antenna array structure. Background Art

[0002] In today's rapidly developing technological era, the communication field is changing with each passing day. With the continuous advancement of technology, especially the rise and development of 5G communication technology, many significant changes have been brought about. The original radio and television communication frequency, such as 862MHz, has gradually been compressed to 600MHz. This change has had a profound impact on many fields.

[0003] In the field of radio and television, this frequency change has triggered a series of chain reactions; due to the adjustment of 5G communication frequency, the channel resources of wireless terrestrial television have been greatly compressed, which has forced many digital TV bands to be re-arranged in most areas, and many have been transferred to the VHF band; however, the traditional antenna array structure is prone to signal instability when receiving VHF band signals in the face of this new frequency band, which affects people's viewing experience. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a high-low frequency digital television antenna array structure to solve the technical problem in the prior art that the traditional antenna array structure is prone to unstable signals when receiving VHF band signals in the face of this new frequency band, thereby affecting people's viewing experience.

[0005] The purpose and effect of the high and low frequency digital television antenna array structure of the utility model are achieved by the following specific technical means:

[0006] A high- and low-frequency digital television antenna array structure includes a PCB circuit board, a connection groove for installation is opened on one side of the PCB circuit board, a VHF low-frequency signal receiving component and a UHF high-frequency signal receiving component are arranged on the top of the PCB circuit board, the VHF low-frequency signal receiving component includes a VHF pull rod array, the UHF high-frequency signal receiving component includes a UHF array, and the VHF pull rod array and the UHF array are arranged on the top of the PCB circuit board.

[0007] In a preferred embodiment, a telescopic portion with adjustable length is provided on the top of the VHF tension rod array.

[0008] In a preferred embodiment, the VHF low-frequency signal receiving component further includes a VHF array end, and the VHF array end is arranged on the top of the telescopic part.

[0009] In a preferred embodiment, a connecting column is provided at the bottom of the VHF pull rod array, and a mounting hole is correspondingly opened at the top of the PCB circuit board, and the connecting column is installed in the mounting hole.

[0010] In a preferred embodiment, the UHF array is arc-shaped, and a plurality of through slots are provided on the UHF array.

[0011] In a preferred embodiment, the UHF high-frequency signal receiving component further includes a blade-shaped signal receiving end, and the blade-shaped signal receiving end is arranged on the top of the UHF array.

[0012] In a preferred embodiment, a mounting groove is provided on the top of the PCB circuit board, and the bottom of the UHF array is inserted into the mounting groove through a connecting piece.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. Through the setting of VHF pull-rod array and UHF array, compatibility with high and low frequency band signals is achieved. When using the antenna array, by vertically setting the UHF array and VHF pull-rod array on the PCB circuit board, they are responsible for the reception of high-frequency and low-frequency signals respectively, which can ensure stable signal reception quality in different frequency bands. Among them, the UHF array adopts an arc-shaped structure, which can effectively improve the standing wave ratio near 470MHz, so that the standing wave ratio within the UHF frequency band bandwidth can be better than 2.0 or less, and the receiving bandwidth of the UHF frequency band can be widened; and the adjustable telescopic part at the top of the VHF pull-rod array can optimize the reception of low-frequency signals by adjusting the length; It solves the problem of unstable signals in traditional antenna arrays and improves people's user experience.

[0015] 2. By adjusting the distance between the UHF array and the VHF pull-rod array, and adjusting the overall length of the VHF low-frequency signal receiving group through the telescopic part, the coupling effect between the two can be enhanced, thereby improving the reception strength of the UHF frequency band. This active adjustment method can effectively resist the interference of external environmental factors on signal quality, ensuring that the antenna can have good reception performance under various circumstances, so that users can still watch TV programs stably in complex usage environments.

[0022] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0023] Example:

[0024] As attached Figure 1 To Attachment Figure 4 As shown:

[0025] The utility model provides a high- and low-frequency digital television antenna array structure, comprising a PCB circuit board 11, a VHF low-frequency signal receiving component and a UHF high-frequency signal receiving component. A connecting groove 12 for installation is provided on one side of the PCB circuit board 11, which provides convenience for the installation of the antenna; the VHF low-frequency signal receiving component comprises a VHF pull-rod array 21, and the UHF high-frequency signal receiving component comprises a UHF array 31. The VHF pull-rod array 21 and the UHF array 31 are respectively arranged on the top of the PCB circuit board 11, so as to achieve full compatibility with high- and low-frequency signals, wherein the VHF pull-rod array 21 is responsible for receiving low-frequency VHF signals, and the UHF array 31 is specially used for receiving high-frequency UHF signals; this high- and low-frequency separation structure gives full play to the respective advantages of the VHF pull-rod array 21 and the UHF array 31, ensures that stable signal reception quality can be obtained in different frequency bands, and meets the user's demand for full-band coverage of digital television signals.

[0026] By adjusting the distance between the UHF array 31 and the VHF pull rod array 21, the coupling effect between the two can be enhanced, thereby improving the reception strength of the UHF frequency band. This active adjustment method can effectively resist external environmental factors such as building shielding, electromagnetic interference, etc. that interfere with the signal quality; and by adjusting the overall length of the VHF low-frequency signal receiving component through the telescopic part 22, the reception of low-frequency VHF signals can be optimized, so that the antenna can be adjusted according to changes in the actual use environment, ensuring that in a complex use environment, users can still stably watch high-quality TV programs, which not only improves the anti-interference ability of the antenna, but also greatly enhances its scope of application and flexibility of use.

[0027] Please refer to Figure 1 and Figure 2 As shown, at the top of the VHF pull rod array 21, there is a telescopic part 22 with an adjustable length, and at the top of the telescopic part 22, there is a VHF array end 23. By adjusting the length of the telescopic part 22, the overall size of the VHF low-frequency signal receiving component can be optimized, thereby improving the reception effect of the low-frequency VHF signal; this adjustable length design is very flexible and practical, and the user can quickly adapt to the best receiving state by simply adjusting the length of the telescopic part 22 according to the actual use environment, such as signal strength, interference, etc.; this not only ensures that high-quality VHF low-frequency signals can still be stably received in complex environments, but also greatly improves the versatility and application range of the antenna. The setting of the VHF array end 23 further optimizes the reception performance of the low-frequency signal. The VHF array end 23 can effectively gather and guide the low-frequency VHF signal, and cooperate with the adjustable telescopic part 22 to form an efficient VHF low-frequency signal receiving component.

[0028] Please refer to Figure 2 and Figure 4 As shown, a connecting column 24 is provided at the bottom of the VHF tension rod array 21, and the connecting column 24 plays an important fixing role; a mounting hole 25 is correspondingly opened at the top of the PCB circuit board 11, and the connecting column 24 is just installed in the mounting hole 25, so that the VHF tension rod array 21 can be firmly installed on the PCB circuit board 11, which not only ensures the stability of the VHF tension rod array 21, but also can effectively transmit the signal from the antenna to the receiving circuit on the PCB circuit board 11. The connecting column 24 serves as a bridge between the antenna and the circuit board, ensuring the smooth transmission of the signal and avoiding the loss of the signal during the switching process. At the same time, this compact structural layout also greatly saves space, making the entire antenna array more compact and coordinated.

[0029] Please refer to Figure 2 and Figure 3As shown, the UHF array 31 adopts an arc-shaped structure. The surface of the UHF array 31 is provided with multiple groups of through grooves, which brings a significant optimization effect for the signal reception of the UHF band. This structure can effectively improve the standing wave ratio near 470MHz, so that the standing wave ratio within the UHF band bandwidth is better than below 2.0, which not only greatly broadens the receiving bandwidth of the UHF band, but also solves the problem of unstable signals prone to traditional antenna arrays; compared with traditional linear antenna arrays, the arc-shaped structure of the UHF array 31 can better adapt to different signal environments. This arc design can more evenly disperse and conduct electromagnetic waves in the UHF band, reduce local concentrated signal interference, and thus improve the overall signal reception quality; at the same time, the arc-shaped structure also gives the UHF array 31 a more elegant and dynamic appearance design, further enhancing the user experience.

[0030] Please refer to Figure 3 As shown, in addition to the UHF array 31, the UHF high-frequency signal receiving component also includes another important component, a knife-shaped signal receiving terminal 32, which is arranged at the top of the UHF array 31; the knife-shaped signal receiving terminal 32 and the arc-shaped structure of the UHF array 31 coordinate with each other to jointly play the optimization effect of high-frequency signal reception, and can effectively capture and guide the electromagnetic wave signal of the UHF frequency band; the knife-shaped signal receiving terminal 32 can collect the signals of the UHF frequency band and transmit them to the UHF array 31. This efficient signal capture and transmission mechanism further improves the overall performance of the UHF high-frequency signal receiving component and ensures that a stable and reliable reception effect can be maintained in various complex signal environments.

[0031] Please refer to Figure 2 As shown, a mounting groove 33 is provided on the top of the PCB circuit board 11, which facilitates the installation of the UHF array 31. The bottom of the UHF array 31 is inserted into the mounting groove 33 through a connector 34, thereby achieving reliable fixation with the PCB circuit board 11; it not only ensures that the UHF array 31 can be firmly mounted on the PCB circuit board 11, but also effectively prevents the problem of loosening or falling off in a complex use environment. The setting of the connector 34 ensures a perfect fit with the mounting groove 33, so that the entire high-frequency signal receiving component can be firmly integrated on the PCB circuit board 11.
