A new miniaturized multi-band transparent antenna for V2X communication

Intelligent transportation services are being developed to enhance road safety, increase traffic efficiency, achieve higher speeds, and alleviate traffic congestion. This article presents the design and simulation results of a novel, compact, transparent patch antenna. The suggested design is designed to cover vehicular communication standards such as DSRC/IEEE 802.11p at 5.9 GHz and cellular V2X (C-V2X) bands. Additionally, it supports other frequency bands, including the C-Band (5.925–6.425 GHz, 7.25-7.75 GHz) and X-Band (7.250-7.750 GHz, 7.90–8.40 GHz, 8.0–8.5 GHz). The antenna operates within the frequency ranges of 5.11–6.44 GHz and 7.25–9.06 GHz, achieving a gain of 2–5 dB and a radiation efficiency of approximately 90% at 5.9 GHz. The antenna is enhanced by adding slots to the patch and utilizing a modified ground plane.
