Problems solved by technology

[0004] When a conventional shark fin antenna is embedded with a transmitting system, it is difficult to obtain guaranteed performance because the performance of the antenna used only for reception is degraded, and it is necessary to ensure the isolation between the antennas and the isolation between the transmitting system and the receiving system

Abstract

A shark fin antenna is proposed 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 A signal receiving 3G / 4G frequency band signals; an AM / FM antenna mounted at the second end of the circuit board and configured to receive AM / FM frequency band signals; a V2X antenna mounted on the side of the AM / FM antenna On the surface, each V2X antenna is spaced apart by a predetermined distance and configured to realize V2X (vehicle-to-external) communication; and a plurality of antennas are positioned between the 3G / 4G antenna and the AM / FM antenna to receive high Signals in the AM / FM band but lower than the 3G / 4G band.

Description

technical field [0001] Teachings according to exemplary embodiments of the present disclosure relate generally to a shark fin antenna, and more particularly, to a shark fin antenna formed from a plurality of antennas arranged to provide various wireless services. Background technique [0002] Conventional shark fin antennas are implemented and used to communicate over two or three of the following types of frequency bands: AM, FM, T-DMB, GPS / Glonass / Galileo / XM / SIRIUS (hereinafter referred to as "satellite Integrated antenna"), Wave, Wi-Fi and 3 / 4G. [0003] The structure of conventional shark fin antennas makes it difficult to achieve isolation between antennas, making it difficult to guarantee performance beyond that of conventionally used stand-alone antennas. Therefore, when multiple types of antennas are embedded in the shark fin antenna, it is difficult to obtain a guarantee for the performance of the system, so that 2 to 3 antennas are embedded for communication using...
