To ensure the success of upcoming vehicular ad hoc networks (VANETs), we are currently developing a 4 × 4 multiple-input multiple-output (MIMO) antenna system utilizing a phased array in a circular configuration. The circular phased array 4 × 4 MIMO antenna generates four radiation patterns with the peak gain at the angle of incident wave by reorganizing the antenna elements. The proposed antenna provides a high level of MIMO channel capacity regardless of the variations in the angle of incident wave, demonstrating that gigabit high-speed communications can be realized using the proposed antenna.
