Abstract

A shark fin antenna equipped with a V2X communication system which ensures high-efficiency performance in a moving vehicle, thereby wirelessly providing various frequency transmitting/receiving signals to a user's vehicle, an adjacent vehicle as desired by the user, and a pedestrian, whereby an integrated telematics service including a safety based service is provided. The shark fin antenna includes a fixing part arranged on which an antenna is installed within an applicable range of its internal space, produces an antenna similar to the form of the fixing part, thereby implementing a small-sized antenna and smoothly receiving signals of various bands due to favorable antenna gain and radiation pattern condition, and combines the antenna gain and radiation pattern condition while providing the forms of an antenna unit and an auxiliary unit, thereby flexibly responding to receiving signals of different bands according to use regions.

First claim

The invention claimed is:

1. A shark fin antenna equipped with a vehicle type V2X communication system, comprising:
a circuit board;
a V2X communication unit mounted on one surface of the circuit board;
a satellite integration system unit mounted on the one surface of the circuit board and disposed to be adjacent to the V2X communication unit;
a fixing part comprising an upper fixing part, a middle fixing part and a lower fixing part;
an antenna part coupled to a top of the fixing part,
wherein the upper fixing part surrounds sides of the satellite integration system unit and externally exposes a top of the satellite integration system unit,
wherein the middle fixing part covers the V2X communication unit, and
wherein the lower fixing part surrounds an area in which an AM/FM magnetic body is accommodated and externally exposes the AM/FM magnetic body, where an AM/FM antenna is connected to the AM/FM magnetic body and where an end of the AM/FM antenna is bent in a non-connection part of the middle fixing part.

2. The shark fin antenna of claim 1 , wherein the V2X communication unit is located at a center of the circuit board.

3. The shark fin antenna of claim 1 , wherein the satellite integration system unit comprises at least one antenna of GPS, Glonass and Galileo.

4. The shark fin antenna of claim 3 , wherein the satellite integration system unit further comprises an XM/SIRIUS antenna.

5. The shark fin antenna of claim 1 , wherein the satellite integration system unit comprises a low-noise amplifier (LNA) and is connected to a plurality of antennas within the satellite integration system unit.

6. The shark fin antenna of claim 1 , wherein the antenna part comprises at least one of a 3G/4G antenna, a V2X passive antenna, an AM/FM antenna and a DMB antenna.

7. The shark fin antenna of claim 6 , wherein the 3G/4G antenna is coupled to a top of the upper fixing part.

8. The shark fin antenna of claim 6 , wherein the middle fixing part comprises a first middle fixing part, a second middle fixing part, a third middle fixing part, and a non-connection part, wherein the third middle fixing part is connected to part of the first middle fixing part and part of the second middle fixing part.

9. The shark fin antenna of claim 8 , wherein the V2X passive antenna is coupled to a top of both of the first middle fixing, part and the second middle fixing part.

10. The shark fin antenna of claim 8 , wherein the AM/FM antenna is coupled to a top of the third middle fixing part and an AM/FM magnetic body.

11. The shark fin antenna of claim 6 , wherein the V2X passive antenna is connected to the V2X communication unit by a cable of 1-10 cm in length.

12. The shark fin antenna of claim 6 , wherein the DMB antenna is coupled to a top of the lower fixing part.

13. The shark fin antenna of claim 1 , further comprising a support located at a bottom of the shark fin antenna and having the circuit board, the fixing part and, the antenna part disposed on one surface of the shark fin antenna.

14. The shark fin antenna of claim 13 , further comprising a casing disposed over the support.

15. The shark fin antenna of claim 14 , wherein the casing has a dome shape having a bottom open and an inside empty.

16. The shark fin antenna of claim 1 , further comprising a DMB magnetic body coupled to a top of the lower fixing part.

17. The shark fin antenna of claim 1 , wherein the V2X communication unit is located on both sides of a top of the middle fixing part.
