Abstract
In this paper, we propose an eight-port/four-resonator slot antenna array with a dual-polarized
function for multiple-input-multiple-output (MIMO) 5G mobile terminals. The design is composed of four
dual-polarized square-ring slot radiators fed by pairs of microstrip-line structures. The radiation elements
are designed to operate at 3.6 GHz and are located on the corners of the smartphone PCB. The squarering slot radiators provide good dual-polarization characteristic with similar performances in terms of
fundamental radiation characteristics. In order to improve the isolation and also reduce the mutual coupling
characteristic between the adjunct microstrip-line feeding ports of the dual-polarized radiators, a pair of
circular-ring/open-ended parasitic structures is embedded across each square-ring slot radiator. The −10-dB
impedance bandwidth of each antenna-element is 3.4–3.8 GHz. However, for −6-dB impedance bandwidth,
this value is 600 MHz (3.3–3.9 GHz). The proposed MIMO antenna offers good S-parameters, high-gain
radiation patterns, and sufficient total efficiencies, even though it is arranged on a high-loss FR-4 dielectric.
The SAR function and the radiation characteristics of the proposed design in the vicinity of user-hand/userhead are studied. A prototype of the proposed smartphone antenna is fabricated, and good measurements are
provided. The antenna provides good features with a potential application for use in the 5G mobile terminals.
