A Switchable or MIMO Antenna for V2X Communication

Abstract

This paper presents a simple 4-port directional antenna as a switchable antenna or MIMO antenna with enhanced gain and interference suppression for V2X communication. A special reflecting wall in cylindrical shape is introduced to the center of the antenna. This wall enhances the gain of the antenna element in one direction while also provides space and flexibility for other antennas. This structure provides a new degree of freedom for optimizing the antenna performance. Simulation and measurement results show that the antenna can perform well in DSRC band.
