Abstract: Abstract Stubs loaded multi band antenna for vehicle-to-vehicle communication operating at 6.5 GHz, 8.5 GHz and 12.5 GHz is presented in this paper. The antenna is based on a rectangular patch loaded with the L shaped stubs for radiating along with the partial ground structure. The higher band 12.5 GHz is achieved by the addition of the L shaped stubs along with the rectangular patch. The partial ground is responsible for the generation of lower band of frequencies from 6.5 to 8.5 GHz. The proposed antenna is modelled using CST Microwave Studio simulator and are validated using Agilent network analyzer (N9925A) and antenna test systems for measuring impedance and radiation characteristics. The outcomes of the proposed antenna are impedance bandwidth of 2.05 GHz, 111 MHz and the gains of 5.09 dBi, 5.06 dBi, with the efficiency of 85.81%, 84.72% in the two resonating bands such as 7.5 GHz (6.5–8.5 GHz) and 12.5 GHz respectively. The radiation patterns exhibited stability within the operating bands, indicating that the proposed stubs loaded multi-band antenna holds promise as a viable solution for vehicle-to-vehicle communication applications which helps in enhanced road safety, traffic management, and overall driving experience.
