Abstract

In this article, a new MIMO smartphone antenna array with compact resonators is introduced for the fifth-generation mobile terminals. The proposed design was developed on an FR4 substrate with relative permittivity εr=4.3 and dielectric loss tangent δ=0.025. The antenna contains eight modified monopole antenna components. The elements are fed by improved L-shaped microstrip feeding lines and cover dual-band frequency rang including 3.30-3.65 GHz and 5.25-5.85 GHz of sub 6 GHz 5G. At 3.47 GHz the Ants. 1, 4, 5, 8 have maximum reflection coefficients of-25 dB while Ants. 2, 3, 6, 7 have reflection coefficients of-20 dB at 5.5 GHz. Essential features of the designed smartphone antenna including S-parameters, radiation patterns, gains, and efficiencies are inspected and sufficient results are observed. The design is highly compact and can be integrated into smartphone circuits.
