The present invention relates to a shark fin antenna equipped with a V2X communication system and, more particularly, to an integrated telematics antenna structure having embedded AM, FM, T-DMB, satellite integrations including GPS, Glonass, Galileo, XM, and SIRIUS, Wave, Wi-Fi, and 3G/4G. The present invention ensures high-efficiency performance in a moving vehicle, thereby being capable of 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. In addition, the present invention arranges a fixing part on which an antenna can be installed within an applicable range of the internal space of a shark fin-type antenna; produces an antenna similar to the form of the fixing part, thereby being capable of implementing an antenna with a small size, 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, and increasing productivity of a product with a concise internal configuration.
