This paper proposed beam steering MIMO antenna for 5G application at 3.5 GHz of mid-band. The beam steering performance is based on the integration of the driven parasitic element and switches. The RT Duroid 5880 is used as substrate with a thickness of 1.57mm. The geometry of the center rectangular patch antenna to achieve the desired resonance frequency which 3.5GHz. The integration of the HPNP 4005 PIN Diode with the parasitic element is tested which the antenna manages to steer the direction at -30°, 0° and +30° with gain of 6.4dBi. However, the driven element achieved the gain, total efficiency, directivity, and bandwidth of microstrip antenna such as 7.106dBi, 75.88%, 8.703dBi and 100MHz. In the proposed design, a simple biasing circuit is employed to control all the PIN Diodes switches. The 2 × 2 MIMO is built at antenna at 3.5GHz mid-band of 5G. The proposed MMO antenna could be potential for 5G application.
