Novel Hexagonal-Shaped Compact Antenna for Vehicular Communication

Intelligent Transportation services are emerging to elevate road safety, enhance traffic efficiency, achieve higher speeds, and alleviate traffic congestion. This study introduces an innovative hexagonal-shaped compact antenna meticulously crafted to encompass the vehicular communication band in DSRC/IEEE802.11p at 5.9 GHz and Cellular V2X (C–V2X) band. The antenna design is rooted in strategically placed slots and a partial ground plane. Operating within the frequency range of 5.26 to 6.74 GHz, the antenna resonates precisely at 5.9 GHz, exhibiting an S11 of −42.66 dB, a gain of approximately 3.01 dB, and an impressive efficiency of about 95%.
