The gain enhanced antipodal Vivaldi antenna (AVA) is implemented in this study for fifth‐generation (5G) communication applications. At first, the conventional AVA is designed and then metamaterial and rectangular corrugations are added to AVA to enhance its gain from 7.75 to 9.53 dB. The designed antenna size is 40 mm × 24 mm × 1.6 mm and it is fabricated on the FR4 substrate. Further, modified AVA with metamaterial and corrugation increases higher cut‐off frequency from 30.62 to 34.52 GHz. The gain of the designed antenna varies between 5 and 9.53 dB over 24.77 to 34.52 GHz and its bandwidth is 9.75 GHz. The designed antenna covers 25 to 29.5 GHz and 31.8 to 33.4 GHz 5G frequency bands. Experimental results and the simulated results are nearly same, which demonstrate that the designed antenna can be used for 5G communication applications.
