Harmonic Suppressed MIMO Antenna for Highly Integrated V2X Communication System
To reduce the electromagnetic interference (EMI) effects in a highly integrated vehicle-to-everything (V2X) communication system, a harmonic-suppressed multiple-input-multiple-output (MIMO) antenna is proposed in the dedicated short-range communication (DSRC) band of the 5.85–5.925-GHz range. The unit element of the MIMO is a circular patch antenna fed in a gap-coupled manner via a pair of $\lambda $ g/4 resonators. Widely used polarization diversity and defected ground structure (DGS) concepts are used for a 4-port antenna system to have improved isolation between individual antennas and hence better MIMO performance in addition to the unique harmonic suppression property. As the number of V2X-compliant vehicles on the road continues to increase, the proposed MIMO antenna is expected to help mitigate EMI in heavy traffic areas with numerous IoT devices.
