Design and Performance Evaluation of Superstrate Microstrip Array Antenna for V2I-DSRC Applications

As the Vehicular Communication systems provides safety applications for autonomous vehicles, a wireless communication device, Antenna plays a vital role in establishing the communication between the vehicles and infrastructures, called as V2I(Vehicle to Infrastructure) Communication. This antenna design is based upon the DSRC(Dedicated Short Range Communication) standards proposed by the FCC(Federal Communications Commission) of US Government which allocates an operating frequency range for the vehicular communications. Microstrip antenna is chosen for its low profile. This paper presents the design and performance analysis of `Superstrate Microstrip Array Antenna', using HFSS software. Where the antenna characteristics: Gain, Directivity, Return Loss and Radiation Pattern are analysed and the reported results are compared with the proposed idea. Finally, it concludes that the proposed antenna design is suitable for an efficient V2I Communication.
