Description

Antenna module

The present invention relates to an antenna module, and more particularly, to an antenna module for connecting to a vehicle-mounted personal computer in which various functions are integrated by modularizing an antenna connected to a navigation, a television, a wireless modem, and the like mounted on a vehicle. It is about.

Hyundai is a society of information and communication, but automobiles have long withheld its benefits. Car audio is the only means of getting information from headquarters, and brake lights, headlights, turn signal horns, etc. are the only means of communicating one's intentions to the outside world. As a communication means, it is "one-way communication", and it is hard to say that it is an advanced information system. With the progress of the current information society, the way of life of humans is constantly changing, and the interior space of automobiles is not only a world of other things, it is accelerating. BACKGROUND ART Autonomous navigation systems, which are equipped with road map network data by themselves, calculate their own positions on a map and display them on a display mounted on a vehicle, are gradually spreading. When real-time dynamic information about traffic congestion, road regulation, accidents, parking lots, etc. is provided to such a navigation system through a mobile information communication system that networked communication devices, roadside communication devices, and information processing centers mounted on automobiles, Evolve into a system with higher added value.

Therefore, in the related art, an antenna for transmitting or receiving radio waves corresponding to each device is provided in a vehicle-mounted personal computer in which a navigation system, audio, TV, video, CD, PDA, and the like have a single device having individual functions as described above. It was individually mounted and connected to the united on-board personal computer.

The vehicle-mounted personal computer is described in detail in "Domestic Patent Application No. 10-2002-0019632, Title: Vehicle Personal Computer System."

However, as antennas connected to a navigation system, a TV, a wireless modem, and the like are connected to a single vehicle-mounted personal computer as in the related art, wiring is complicated and manufacturing costs increase.

In addition, the installation position of the rear glass in a passenger car is installed at an angle capable of receiving radio waves, so that the navigation antenna may be modularized and applied with audio using a glass antenna. As they are installed in close proximity, the radio wave reception rate is lowered, which implies that a glass antenna cannot be applied.

Accordingly, an object of the present invention is to solve the above problems, an antenna that can be connected to the vehicle-mounted personal computer by a single cable by modularizing each of the transmit and receive antennas connected to the vehicle-mounted personal computer having multiple functions To provide a module.

The present invention for achieving the above object,

An antenna connected to a vehicle-mounted personal computer, characterized in that the navigation, television and wireless modem antennas are configured as one module.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a simplified configuration diagram of an antenna module applied to the present invention, Figure 2 is a perspective view of the antenna module mounting according to the present invention.

As shown in FIG. 1, the antenna module includes: a GPS antenna 20 for receiving information transmitted from the GPS satellites 10; A TV antenna 30 for receiving terrestrial waves such as a television; A wireless modem antenna 40 for transmitting and receiving mobile communication and wireless Internet signals; An antenna module (50) for receiving and amplifying the GPS antenna (20), TV antenna (30) and wireless modem antenna (40) signals; It consists of a vehicle-mounted personal computer 60 that receives the signal received from the antenna module 50 and performs a corresponding function.

As shown in FIG. 2, the antenna module having the above configuration is provided at a predetermined location outside the vehicle to increase the radio wave reception rate, and is prevented from inflow of foreign substances from the outside and is processed to block radio interference. Insert it into a case (e.g. rubber case: 80).

Accordingly, the GPS antenna 20 is inserted into the case 80 as shown in FIG. 2 and connected to the signal input unit of the antenna module 50, and the television antenna 30 has a high reception rate (eg, 45 °), and is formed in a predetermined position outside the case 80 to be connected to the signal input unit of the antenna module 50.

In addition, the wireless modem antenna 40 is provided at a predetermined position outside the case 80 and connected to the signal input unit of the antenna module 50.

The signal received from the GPS antenna 20, the television antenna 30 and the wireless module antenna 40 is input to the signal input unit of the antenna module and amplified to a predetermined frequency, and then to a single antenna cable (not shown). It is connected to the vehicle-mounted personal computer 60 by the.

Accordingly, the vehicle-mounted personal computer 60 receives a signal received from the antenna module 50 and performs a corresponding function.

As a result, by integrating and modularizing the antennas for receiving the respective airwaves into a single antenna, GPS and TV reception performance can be improved, and antenna cables can be reduced, thereby reducing manufacturing costs.

As described above, the present invention provides an antenna module that can be connected to a vehicle-mounted personal computer with a single cable by modularizing each of the transmitting and receiving antennas connected to the vehicle-mounted personal computer having various functions, thereby providing GPS and television. It is possible to improve the reception performance and to reduce the antenna cable, thereby reducing the manufacturing cost.
