High Performance V2X Antennas Designed in Integrated Shark-fin Environment

A new high performance two-element V2X antenna array is presented, which is interspersed between two LTE antennas and designed in shark-fin environment. By using the specific designed lines and the closely EM coupling features, the desired current distributions in the element are achieved. Its high performance, with 10dB impedance bandwidth of 5% (5.7-6.0GHz), port isolation of 23 dB under the gain of 5.8dBi in elevation plane and the variation less than 5dBi in azimuthal plane, are finally verified by simulations and measurements, showing the great potential applications in automobile wireless communications.
