Design of a V2X Vehicle Antenna

In this paper, we propose V2X shark-fin antenna that operated on vehicle roof. Propose antenna is composed of AM/FM Radio broadcasting, Digital Media Broadcasting (DMB), Global Positioning System (GPS), and dual V2X (Vehicle-to-everything) antennas. Propose antenna has -1.2 dBi in AM/FM Radio band, 5.8 dBi in DMB band, and 28 dBic in GPS band (Including Low Noise Amplifier). Especially designed antenna has -2.3 dBi average gain in V2X 1, -2.9 dBi average gain in V2X 2. V2X antenna's communication distance is 995~1329 m in Line-Of-Sight [LOS].
