Abstract
This paper presents a hybrid dual-polarized conformal dielectric resonator (DR) antenna (DRA) array for 5G millimeter wave mobile terminals. Each polarization has two resonant modes: the dielectric resonant mode and the slot mode. The combination of these resonant modes realizes wide impedance bandwidth (24.2-36.3 GHz) to cover 5G millimeter (a) wave band n257 (26.5-29.5 GHz), n258 (24.25-27.5 GHz), and n261 (27.5-28.35 GHz). Besides, due to the flexible three-dimensional (3D) structure of DRs, the proposed antenna array can be adapted into the form of a phone frame. Thus, the proposed antenna can be conformably placed in the frame of the mobile terminal. In this design, the curved glass in the frame of the mobile terminal also works as an inherent portion of the DR. Therefore, the glass cover will not place a negative effect on the proposed antenna array as in conventional design approaches.
