Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of satellite television, and in particular to a 5G satellite television multi-mode frequency division multiplexing antenna. Background Art
[0002] Satellite television is a television system that uses communication satellites to transmit and relay television programs. The television programs are sent from a certain ground station to the communication satellite, and then downlinked by the communication satellite to other ground stations or individual receiving terminals for receiving and watching television. When receiving satellite television at the terminal, a dish antenna receiving system is required to receive satellite signals.
[0003] The dish antenna receiving system of satellite television consists of: a parabolic antenna, a feed, and a low-noise block downconverter (LNB). Among them, the parabolic antenna reflects and converges the energy of satellite signals in the sky into a focus; the feed is a horn that collects satellite signals set at the focus of the parabolic antenna. The feed refers to the source that feeds energy, and it collects all the energy converged to the focus; the low-noise block downconverter (LNB) downconverts and amplifies the satellite signals sent by the feed, and then transmits them to the satellite receiver. The lower the noise figure of the low-noise block downconverter (LNB), the better. The feed and the low-noise block downconverter (LNB) are generally integrated together and fixed on the parabolic antenna during use.
[0004] Digital satellite television is a form of radio and television that uses geostationary satellites to transmit digitally encoded and compressed television signals to the user side; it directly transmits digital television signals to users' homes, that is, in the Direct to Home (DTH) mode. DTH can directly provide user authorization and encryption management, and carry out advanced television services such as digital television, pay-per-view television (PPV), and high-definition television, without being restricted by intermediate links. Due to the large satellite launch power in the DTH mode, a smaller dish antenna can be used for reception, and ordinary families can use it.
[0005] In addition, the Beidou satellite positioning system is a global satellite navigation system independently designed, developed, and built by China; at present, domestic direct broadcast satellite television generally uses the KU band for transmission, and end users can receive relevant positioning signals through a Beidou receiving antenna.
[0006] The fifth generation of mobile communication technology (5th Generation Mobile Communication Technology, abbreviated as 5G) is a new generation of broadband mobile communication technology with the characteristics of high speed, low latency, and large connection. 5G communication facilities are the network infrastructure for realizing the interconnection of people, machines, and things. End users receive signals through a dedicated 5G antenna.
[0007] DTMB (Digital Terrestrial Multimedia Broadcast), formerly known as DMB-T / H (Digital Multimedia Broadcast-Terrestrial / Handheld), is a digital video broadcast standard in China, which is a standard for digital TV and mobile digital radio formulated by the People's Republic of China. This standard will serve half of the TV viewers in China, especially in suburban and rural areas.
[0008] In summary, with the rapid development of information technology, there is a market demand for integrating the above technologies in more usage scenarios. How to form a product that can be flexibly configured after integrating various technologies is the main product pre-research direction for relevant practitioners. Summary of the Invention
[0009] To overcome the deficiencies of the prior art, the present invention provides a 5G satellite TV multi-mode frequency division multiplexing antenna.
[0010] A 5G satellite TV multi-mode frequency division multiplexing antenna includes a multi-signal mixing unit, and a direct broadcast satellite TV signal processing unit, a Beidou satellite signal processing unit, a terrestrial digital TV signal processing unit, and a 4G / 5G network signal processing unit that are electrically connected to the multi-signal mixing unit respectively.
[0011] Among them, the direct broadcast satellite TV signal processing unit is used to obtain the first intermediate frequency satellite signal; the Beidou satellite signal processing unit is used to obtain the satellite positioning signal; the terrestrial digital TV signal processing unit is used to obtain the terrestrial digital TV signal; the 4G / 5G network signal processing unit is used to obtain the 4G / 5G network signal; the multi-signal mixing unit mixes the first intermediate frequency satellite signal, the satellite positioning signal, the terrestrial digital TV signal, and the 4G / 5G network signal, and transmits them to the terminal receiving device through a coaxial cable.
[0012] Optionally, the multi-signal mixing unit, and the direct broadcast satellite TV signal processing unit, the Beidou satellite signal processing unit, the terrestrial digital TV signal processing unit, and the 4G / 5G network signal processing unit that are electrically connected to the multi-signal mixing unit respectively are integrated within the same device housing.
[0013] The 5G satellite TV multi-mode frequency division multiplexing antenna provided by the present invention integrates the feed and LNB in the satellite antenna receiving system, the Beidou satellite signal processing unit, the terrestrial digital TV signal processing unit, and the 4G / 5G network signal processing unit in view of the development trend of the integration of existing digital communication technologies. When in use, it needs to cooperate with a satellite parabolic antenna to form a complete usage scenario. At the same time, the processing units such as terrestrial digital TV signals can be flexibly selected to meet the actual application requirements in specific products. Compared with the prior art, the 5G satellite TV multi-mode frequency division multiplexing antenna can be a multi-signal receiving device, having the advantages of convenient installation, beautiful appearance, low comprehensive cost, and high signal quality.
