Abstract:This project is under the thrust area of “Develop Cyber-resilient Mitigation Methods”. The main purpose of this project is developing a smart antenna system to enhance cybersecurity of vehicle-to-everything (V2X) and Cellular V2X (C-V2X) communication in 5.9 GHz frequency band. Our compact and low-cost antenna system comprises a circular array of four antenna elements with specially designed patterns which support both multiple inputs multiple outputs (MIMO) and array beamforming operations. It is also capable for rejecting strong interference or jamming signals due to its specially designed antenna element patterns. Our approach is superior to conventional pure MIMO antenna or phased array antenna design approaches, and thus enhancing V2X communication reliability and security. A protype of the developed antenna system design was fabricated and measured. The measurement results were compared with performance predicted from numerical model simulations with excellent agreement. The developed V2X/C-V2X antenna systems can be used with any existing V2X/C-V2X radios for communication or navigations with enhanced security against multi-path or malicious interferences.
