Abstract— The urgent need to mitigate traffic problems such as
accidents, road hazards, pollution and traffic jam have strongly
driven the development of vehicular communications. DSRC
(Dedicated Short Range Communications) is the technology of
choice in vehicular communications, enabling real time
information exchange among vehicles V2V (Vehicle-to-Vehicle)
and between vehicles and infrastructure V2I (VehicleInfrastructure).
This paper presents a receiving antenna for a
single lane DSRC control unit. The antenna is a non-uniform
array with five microstrip patches. The obtained beam width,
bandwidth and circular polarization quality, among other
characteristics, are compatible with the DSRC standards, making
this antenna suitable for this application.
