Vehicle Communication: Low-Profile Dual-Frequency Antenna

The Problem:
To prevent traffic accidents, U.S Department of Transportation plans to enforce future automobiles to incorporate dedicated short-range communication devices (DSRC), which accommodates vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communications. To date, there has not been an antenna small or efficient enough to transmit at the necessary frequencies to communicate from V2V or V2I. DSRC provides various safety features in the vehicle, but it is not suitable to accommodate the mobile entertainment system and autonomous driving systems that can be realized by 5G network.

The Solution:
Researchers at the University of Alabama have developed a dual frequency antenna that can simultaneously operate on the DSRC and 5G frequencies. There has not yet been an attempt to create a dual frequency antenna specifically dedicated to DSRC and 5G. This combination allows for a greater range of applications without requiring additional hardware. Utilizing both DSRC and 5G in vehicles will not only allow the vehicle to be safer but also more entertaining.


  • Both DSRC and 5G have extremely low latency.
  • Combining the two allows for a greater range of applications without additional hardware.
  • First commercial use of 5G in vehicles.
