A Compact Dual-Band Antenna for Enhanced Vehicle-to-Vehicle Communication

This study presents a dual-band microstrip patch antenna specifically designed for Vehicle-to-Vehicle (V2V) communications. Simulated on an FR-4 substrate and incorporating strategically placed slots along the feedline, the antenna resonates at critical frequencies (0.915 GHz and 3.5 GHz) essential for various V2V scenarios. The design achieves effective impedance matching, showcasing bidirectional radiation patterns with a peak gain of 4.03 dBi at 3.5 GHz. Furthermore, optimized surface current distribution enhances the antenna’s adaptability to diverse vehicle orientations. With radiation efficiency values surpassing 80% in each operational band, the antenna efficiently converts electrical power into radiated signals. The proposed antenna stands out as a versatile and dependable solution for V2V communications, marking a significant contribution to antenna technology for vehicular communication applications.
