SIW-fed Metallic Cap Loaded Cylindrical DRA Array Antenna for 5G mm-wave Applications

In this article, a cylindrical dielectric resonator array antenna fed with a SIW (substrate integrated waveguide) based Wilkinson power divider network is proposed for 5G mm-wave application. The design consists of four cylindrical dielectric resonator antennas (DRAs) that are mounted on the top of the four slots, two on each arm of a 1:2 Wilkinson power divider. Ansys HFSS simulation results confirm that the proposed array operates at 28 GHz with a bandwidth of 330 MHz with good monopole type radiation and a peak gain of 9.9 dBi.
