Abstract:
This paper presents a dual-polarized dielectric resonator antenna (DRA) achieving more than 40% fractional bandwidth, thus the 5G bands n257 and n260 are covered with a single antenna. Hence, the system cost is considerably reduced, since only one antenna array system is required. The bandwidth could be reached thanks to the wideband monopoles and differential feeding enabling hybrid operation in monopole and DRA mode. The antenna uses a standard two metal layer PCB process and 3D printing for the fabrication of the dielectric resonators, reducing the number of PCB layers and the overall production cost. The prototypes of a single element and 2 x 2 array show a maximal gain of 7.1 dBi and 10.4 dBi respectively.
