High Gain Switchable Dielectric Resonator Antenna Array for 5G Applications

This paper presents the findings of high gain switchable dielectric resonator antenna array (DRA). A design is formed by incorporating DRA with a combination of two driven DRs using power divider network and phase switching. The radiation pattern and the reflection coefficient were simulated using ANSYS HFSS ver. 16. As the result, the switchable high gain DRA array achieved a maximum gain and bandwidth of 12.8 dBi and 3.1 GHz (18%), respectively. Moreover, the measured high gain switchable DRA array is able to steer at ±30° by using only 2 ports. Hence, the switchable DRA array is capable to cover 60° sector which is considered suitable for 5G applications.
