Telecommunication technology is in preparation for the 5th generation (5G). One of the components that play an essential role is an antenna. The characteristics of an antenna that is small in size, wide bandwidth, and uses the Multiple Input Multiple Output (MIMO) system are needed to be used on a 5G network. In this research, a 2×2 MIMO antenna will be designed for 5G networks on cellular devices that work on Ka-Band frequencies of 25-27 GHz. The quasi-yagi microstrip antenna has been chosen for design because it can meet the 5G network's needs. The Rogers RO4350B substrate with a thickness of 0.762 mm and relative permittivity of 3.66 is used in antenna design. This research consists of three antenna simulation steps using CST Studio Suite, namely antenna design, the antenna balun design, and antenna performance optimization. The results show that the simulation of the MIMO antenna has met the expected specifications. The MIMO antenna has return loss less than -10 dB at Ka-Band with the frequency of 25-27 GHz, the return loss less than -10 dB, mutual coupling less than -20 dB, port impedance approaching 50 Ω, gain in the range of 7.1539.457 dBi, and directional radiation pattern.
