New Design of High-Gain Beam-Steerable Dipole Antenna Array for 5G Smartphone Applications

Abstract

This paper proposes a new design of high-gain beam-steerable dipole antenna array for fifth generation (5G) smartphone applications. This 5G antenna was designed used RT Duroid 5880 substrate with dimension size 60×130×0.787 mm3. It consists of 10 dipole antenna elements to a linear array form that smartphone can be configured at the top portion of a smartphone PCB. Simulated show results the proposed 5G antenna is working in the frequency range of 34.875–42.000 GHz, providing 7.125 GHz or 18.75 % of impedance bandwidth. The proposed of 5G antenna reaches gain 13 dBi, and produces a 3 dimensional beam steerable characteristics in the entire operational frequency. The proposed antenna also has mutual coupling characteristic between its elements of less than -10 dB.
