Abstract
A 4×4 MIMO antenna for 5G NR mobile handsets application is proposed in this article. A monopole antenna joints with loop antenna, edge perturbation and asymmetric co-planar waveguide (ACPW) feeding structure is designed to be operated in 5G NR FR1 (3300MHz-3600MHz and 4800MHz-5000MHz) bands. A prototype of the proposed antenna with 10.2 mm in length and 2.8 mm in width is fabricated and investigated experimentally. The polarization diversity is used to arrange the four antennas setup. The experimental results indicate that the isolation (S21) between the antennas is more than 20dB, and the envelope correlation coefficient (ECC) is less than 0.02. The specific absorption rate (SAR) for an input power of 23dBm in 5G NR FR1 band meet the SAR limit of 1.6 mW/g of FCC regulatory limit.
