The designed and fabricated patch antenna covers both dedicated short‐range communication (DSRC) and Fifth Generation (5G) millimeter‐wave (mmW) bands for advanced telematics. The fabricated antenna has a small volume of 2.7λ H × 2.6λ H × 0.15λ H , where λ H is the air wavelength of the highest operating frequency. The antenna performances, such as S‐parameters, the realized gain at boresight (RG 00 ), antenna radiation efficiency, and radiation patterns, are reported. The simulated results are in good agreement with the measured ones. Despite the fabricated antenna's compactness, port isolation higher than 31 dB was achieved. Not only high RG 00 s of 6.8 and 12 dBi were obtained at DSRC and 5G mmW bands, respectively, but also an efficiency greater than 90% was observed at both frequency bands. Lastly, the fabricated antenna shows better performance than the previously reported dual‐band antennas.
