The increase in human population is directly proportional to the use of smart devices in everyday life. The increase in the use of smart devices must be in accordance with the quality of cellular telecommunications services. 4G cellular technology is already felt to be insufficient with demand that will continue to grow with the development of IoT technology that will connect many devices in the world so that greater bandwidth and data rates are needed. The development of 5G cellular technology is expected to answer future challenges. In this final project, a V2X antenna is designed for the application of 5G in the sub6 GHz frequency band with a working frequency of 3.5 GHz. The proposed V2X antenna design uses a Vivaldi-rectangular cavity using a modified Marchand balun feeder. Marchand balun is chosen because it produces wide bandwidth, small losses, and is easy to implement in planar form. This V2X antenna will be arranged in a 10x10 MIMO configuration consisting of 20 single antenna ports. The antenna will be shorted to the ground plane in the form of a 10-sided prism. In each facet of the prism, 2 antennas will be arranged with a 90° difference of position, so as to produce double polarization. Successfully simulated and fabricated the design of a 10 x 10 V2X MIMO antenna in the form of Vivaldi with a modified Marchand balun feeder. The antenna works from a frequency range of 3.4 – 3.6 GHz which includes a working frequency of 3.5 GHz with an average bandwidth of 313.75 MHz. The average gain value for each antenna is 5.58 dB.
