    This paper presents the findings of a steerable higher order mode (TEy 1δ3) dielectric resonator antenna with parasitic elements. The beam steering was successfully achieved by switching the termination capacitor on the parasitic element. In this light, all of the dielectric resonator antennas (DRAs) have the same dielectric permittivity similar to that of ten and excited by a 50 microstrip with a narrow aperture. The effect of the mutual coupling on the radiation pattern and the reflection coefficient, as well as the array factor, was investigated clearly using MATLAB version 2014b and ANSYS HFSS version 16. As the result, the antenna beam of the proposed DRA array managed to steer from −32◦ to +32◦ at 15 GHz. furthermore, the measured antenna array showed the maximum gain of 9.25 dBi and the reflection coefficients which are less than −10 dB with the bandwidth more than 1.3 GHz, which is viewed as desirable for device-to-device communication in 5G Internet of Things applications.

    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 thickness 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 -30º, 0ºand +30ºwith gain of 6.4dBi. In the proposed design, a simple biasing circuit is employed to control all the PIN Diodes switches. The proposed MMO antenna could be potential for 5G application.
