4 is a block diagram briefly showing a GNSS and RFID signal amplifying apparatus for a vehicle according to another embodiment of the present invention.

Referring to FIG. 4, unlike the embodiment shown in FIG. 3, an external antenna is separately provided for the GNSS and the RFID. That is, the external antenna 200-1 for RFID and the external antenna 200-2 for GNSS (for example, GPS) may be separately provided. According to this embodiment, the diplexer 121 shown in FIG. 3 can be omitted.

Next, an operation and effect according to embodiments of the present invention will be described. For example, an external antenna 200 capable of receiving an external signal of the vehicle may be attached to the vehicle windshield 20.

The main body 100 can be installed in a glove box G (see Fig. 2) inside the vehicle. The RFID card 30 (see FIG. 2) can be inserted and fixed to a holder member 103 (see FIG. 2) provided at the upper end of the main body 100.

Meanwhile, a plurality of built-in antennas 130 and 150 (see FIG. 3) may be provided in the main body 100 to radiate amplified signals to the inner space of the vehicle.

For example, in the case of a GPS signal, the GPS signal may be amplified in the main body 100 and then radiated into the internal space of the vehicle using the built-in antenna.

Accordingly, it is possible to smoothly receive the amplified GPS signal by using a navigation device, a smart phone, or the like in the vehicle, and use the location-based service.

As another example, in the case of an RFID signal, unlike the above-described GPS signal, transmission and reception are performed at the same frequency, so there is a need to separate the paths of transmission and reception signals.

As shown in FIG. 2, the RFID tag 30 is mounted on a holder member 103 (see FIG. 2) of the main body 100, 2) receives and reflects a radiated signal, and can modulate and transmit information when reflected.

At this time, the signal reflected from the RFID card 30 (see FIG. 2) can be amplified after being received by the built-in antenna built in the main body 100.

The amplified signal can be transmitted to the RFID reader outside the vehicle by the external antenna 200.

On the other hand, the RFID reader receives the signal and instructs the RFID reader 30 to open the access blocking bar according to the information of the RFID card 30 (see FIG. 2), and the vehicle can enter the inside of the corresponding facility.

As described above, according to the configuration and the function of the present invention, a GNSS (Global Navigation Satellite System) signal outside the vehicle can be amplified and radiated into the vehicle.

In recent years, a lot of metal tinting has been included in such a thin film, and this metal component attenuates the GNSS signal including the GPS and the RFID signal, Which is a cause of deterioration. According to the embodiment of the present invention, it is possible to improve the reception state of the GNSS signal and the RFID signal even in a vehicle to which the tinting film is applied as described above.

As described above, the vehicle GNSS and the RFID signal amplifying apparatus according to the preferred embodiment of the present invention have been described.

It is to be understood that the above-described embodiments are to be considered in all respects as illustrative and not restrictive, and the scope of the present invention will be indicated by the appended claims rather than by the foregoing detailed description. It is intended that all changes and modifications that come within the meaning and range of equivalency of the claims, as well as any equivalents thereof, be within the scope of the present invention.
