Shark pin antenna

1. A shark fin antenna, the antenna comprising:

a base;

a circuit board mounted on the base;

a 3G/4G antenna mounted at a first end of the circuit board and configured to receive a signal of 3G/4G band signal;

an AM/FM antenna mounted at a second end of the circuit board and configured to receive an AM/FM band signal;

V2X (Vehicle to Everything) antennas mounted at a lateral surface of the AM/FM antenna, each being spaced apart at a predetermined distance and configured to realize V2X communication; and

a plurality of antennas positioned between the 3G/4G antenna and the AM/FM antenna to receive a hand signal higher than the AM/FM band signal, but lower than the 3G/4G band signal,

wherein the AM/FM antenna includes a spring assembly vertically mounted at the circuit board, a metal antenna coupled to an upper side of the spring assembly, and a magnetic substance positioned at a bottom side of the metal antenna, and

wherein the metal antenna is configured in a manner such that a part of the metal antenna rises upwards by being bent into a U shape or a V shape.

2. The shark fin antenna of claim 1 , wherein the plurality of antennas is mounted at a shade area, a space being that signals transmitted and received through the AM/FM antenna are non-existent.

3. The shark fin antenna of claim 1 , wherein the 3G/4G antenna includes two horizontally-arranged antennas of a main antenna and a sub antenna.

4. The shark fin antenna of claim 1 , wherein one of the V2X antennas is arranged at a left side of the AM/FM antenna and the other V2X antenna is arranged at a right side of the AM/FM antenna, each being spaced apart at a predetermined distance.

5. The shark fin antenna of claim 1 , wherein the spring assembly includes a coil spring, a bottom electric conductor coupled to a bottom side of the coil spring to receive, from the circuit board, a current necessary for radiation, and an upper electric conductor coupled to an upper side of the coil spring and connected to the magnetic substance.

6. The shark fin antenna of claim 1 , wherein the plurality of antennas includes a satellite integrated antenna mounted between the 3G/4G antenna and the AM/FM antenna to receive a signal of satellite frequency band.

7. The shark fin antenna of claim 6 , wherein the plurality of antennas includes a DMB (Digital Multimedia Broadcasting) antenna mounted between the satellite integrated antenna and the AM/FM antenna to receive a signal of DMB band.

8. The shark fin antenna of claim 6 , wherein the satellite integrated antenna is realized to communicate through satellite frequency bands of GPS (Global Positioning System), Glonass, Galileo, XM and SIRIUS.

9. The shark fin antenna of claim 6 , wherein the satellite integrated antenna is realized to further receive a signal of satellite radio frequency band.

10. The shark fin antenna of claim 6 , wherein the satellite integrated antenna includes a satellite radio reception antenna configured to receive a signal of satellite radio frequency band, and a satellite coordinate reception antenna positioned at the satellite radio reception antenna and configured to receive a signal of satellite radio frequency band.

11. The shark fin antenna of claim 6 , wherein a groove is formed at the circuit board, and the groove is mounted with the satellite integrated antenna.

12. The shark fin antenna of claim 6 , wherein the shark fin antenna is formed with two diplexers configured to combine and separate a signal received through the satellite radio reception antenna and a signal received through the satellite coordinate reception antenna at a circuit board area formed with an electronic circuit connected to the satellite integrated antenna.
