Abstract

The utility model relates to a coaxial cable with an antenna. The coaxial cable with the antenna includes the antenna and a coaxial cable. A radio frequency distributor is arranged in the coaxial cable. An input terminal of the radio frequency distributor connects with a copper core on one end of the coaxial cable. An output terminal of the radio frequency distributor connects with a copper core on the other end of the coaxial cable. Another output terminal of the radio frequency distributor connects with a conductor in the antenna. The coaxial cable with the antenna has a function of sending and receiving wireless signals, thereby enlarging the covering range of wireless signals, improving intensity of the wireless signals, and lowering the cost of covering wireless network to terminals.

Description

A kind of coaxial wire with antenna

Technical field

The utility model relates to a kind of data transmission cable, specifically is to have antenna that receives the emission wireless signal and the data transmission cable that coaxial wire is combined as a whole.

Background technology

At present, people pay close attention to respectively the function of antenna and coaxial wire is improved.Below be respectively to the introduction of the background technology of antenna and coaxial cable.

Along with the fast development of information communication industry, the scope of application of coaxial cable more and more widely.Add the accelerated development of the integration of three networks (telecommunications, computer and broadcasting and television network), requiring of communications is various informative.And the first step of the integration of three networks is to realize that network signal and broadcast television signal merge mutually, this is realized by the problem that the transmission on the coaxial wire mainly solves is exactly that existing cable network is become two-way interactive network from the transmission of unidirectional broadcast type, this is the subject matter that solves, access network with one family is an example, at first radio and TV operator's server apparatus merges network signal and TV signal mutually at corridor, next utilizes coaxial cable to be transferred to home terminal, carry out the separation of signal then, realized to surf the Net by coaxial cable like this and made a phone call to see TV.

Antenna is a kind of converter, and it is transformed into the electromagnetic wave of propagating to the guided wave of transmission above-the-line promotion in unbounded media (normally free space), perhaps carry out opposite conversion.In wireless device, be used for emission or receive electromagnetic parts.Engineering systems such as radio communication, broadcasting, TV, radar, navigation, electronic countermeasures, remote sensing, radio astronomy, every electromagnetic wave that utilizes transmits information, all relies on antenna to carry out work.Nowadays, the radio network technique sustainable development, the status is also more and more important.There is inevitably technical barrier such as distance, position and interference in existing wireless network.With the family is example, and wireless network covers owing to be subjected to wall, multiple interference such as area cause in some room or some Local Area Network signal very poor.

Summary of the invention

The utility model is at the deficiencies in the prior art, a kind of cable of better transmission data is provided, this cable can transmission of electric signals, again can transmitting wireless signals, being about to wireless signal restores from coaxial cable, send into user's application apparatus, the maximization that reaches wireless network covers purpose.

The technical solution adopted in the utility model:

A kind of coaxial wire with antenna comprises antenna and coaxial cable, be provided with the radio frequency distributor in the described coaxial cable, the input of radio frequency distributor is connected with an end copper core in the coaxial cable, output of radio frequency distributor is connected with the other end copper core in the coaxial cable, and another output of radio frequency distributor is connected with the conductor in the antenna.

The beneficial effects of the utility model are: this cable has emission and receives the function of wireless signal, this technology has well been avoided the technical barrier of wireless signal, make the wireless signal coverage enlarge, improved wireless signal strength, and reduced the cost that wireless network covers terminal, made the wireless network range of application enlarge.While is along with the enforcement of the integration of three networks, this cable has not only made things convenient for the user in the transformation of terminal, also bring very big facility (once construction can be finished the function of wireless network and broadcast television signal) for installation, and obviously reduced installation workload, improve installation rate and efficient, reduced construction cost.

Description of drawings

Fig. 1 is an outside drawing of the present utility model;

Fig. 2 is a sectional structure chart of the present utility model.

Embodiment

Below in conjunction with accompanying drawing the utility model is further described.

As shown in Figure 1, a kind of coaxial wire with antenna comprisesantenna 5 and coaxial cable, and coaxial cable is by havingoversheath 4,screen 3, insulating barrier 2 andcopper core 1 successively in external, andoversheath 4 can adopt various PVC protective cover materials

As shown in Figure 2, in coaxial cable, be embedded with radio frequency distributor 7, the input of radio frequency distributor 7 is connected with anend copper core 1 in the coaxial cable by conductor lines 6, an output of radio frequency distributor 7 is connected with otherend copper core 1 in the coaxial cable by conductor lines 8, be that one of radio frequency distributor 7 come in and go out end and an output are connected in series two sections copper cores in the coaxial cable, another output of radio frequency distributor 7 passes through conductor lines 9 and is connected withconductor 10 in theantenna 5.

The process of this cable transmission signal is: at first by the coaxial wire transmitting radio frequency signal, be divided into the two-way radiofrequency signal through the radio frequency distributor then, lead up to coaxial cable transmitting radio frequency signal (or being the signal of telecommunication), another road becomes wireless signal by this emission of radio frequency signals of sky bundle of lines; Antenna can receive wireless signal simultaneously.This cable performance index is as shown in the table:

Claims (1)

1. the coaxial wire with antenna comprises antenna and coaxial cable, it is characterized in that:

In described coaxial cable, be provided with the radio frequency distributor, the input of radio frequency distributor is connected with an end copper core in the coaxial cable, output of radio frequency distributor is connected with the other end copper core in the coaxial cable, and another output of radio frequency distributor is connected with the conductor in the antenna.
