DUAL ANTENNA FOR IoV APPLICATIONS BASED ON 802.11bd

Abstract

The Internet of Vehicles (IoV) is a development in the transportation industry that makes the ITS (Intelligence Transportation System). This system is based on two standards: Dedicated Short Range Communication (DSRC) and Vehicle to Everything (V2X) in which IEEE 802.11bd 2022 is the latest evolution of radio access technologies for V2X communications. Operating in two bands of 5.9 GHz and 60 GHz, the advanced IoV antennae face the challenge of the large gap between two resonant frequencies. In this study, a dual antenna is proposed with one being a circular patch to achieve a resonance of 5.9 GHz and the other being a 1x2 array structure to make a 60 GHz band. Using a composed structure of a shorting pin and DGS (Defected Ground Structure), the proposed antenna gets not only a compact size but also wide bandwidths, good gains, and high radiation efficiencies for both bands of IoV communication. All results are validated using CST simulation software.
