    The Dedicated Short Range Communications (DSRC) band (5.85-5.925 GHz) allocated for vehicle-to-vehicle (V2V) communication provides limited opportunities for high speed data transfer. Alternatively, FCC plans to allocate millimeter-wave spectrum for 5G V2V communication. In this paper, we present a novel dual-band dual linearly-polarized antenna array for both DSRC and 28 GHz communications. For each band, we optimized antenna gain and number of elements to maximize range and data rate. The designed array has dual linear polarization and is fed with a simple quarter wave transformer. Due to large available connector’s size, a Wilkinson power divider is designed to combine adjacent elements. Infinite array simulation show that the array is well matched (S11 < -10 dB) from 5.85 to 6.48 GHz, and from 17.29 to 29 GHz. The realized gain at both frequency bands is neartheoretical.
