Performance analysis of printed antenna on different novel substrates to enhance V2V communication in future

Abstract In recent years, advancement in wireless technologies, communication in automotive vehicles has witnessed a tremendous growth in the market. All the sophisticated wireless services offered depends on the type of antenna used in it. The researchers in antenna community are trying very hard to improve the performance of the systems by making smaller antenna devices; however they face both scientific and technical limits. Other alternative approach is to use of novel materials for patch and substrate to adhere higher performance and better functionality. In this paper rectangular patch antenna with stepped ground structure is proposed and its radiation characteristics are analyzed for different dielectric substrates like Si3N4, Al2O3, BN, Quartz and Silica. This study will facilitate researchers to get a clear idea on the patch and substrate material that can be used for V2V applications. The proposed CNT patch antenna on Si3N4 substrate resonates at 5.9 GHz is designed and simulated results show that the minimum return loss of -37 dB is achieved with maximum gain of 6.87. In Addition, the proposed antenna also achieves an omni-directional radiation pattern with maximum radiation efficiency of 89%.
