摘要

This article describes a novel spiral-shaped microstrip patch 2 × 2 MIMO antenna for 5G (n258) and satellite applications. The proposed antenna (A4) comprises a dual-band parallel arrangement of the antenna ports that allows us to enhance isolation to ˂− 30 dB with an impedance bandwidth of 31.79% (19.82–27.31 GHz) and 14.23% (31.07–35.83 GHz) at resonant frequency 26.29 GHz and 32.64 GHz, respectively. Dual-port radiating element based on the meandered-shaped slot between the ports and increased for bandwidth, peak gain, and isolation improvement. The total size of the dual-port MIMO antenna is 30 × 30 × 1.6 mm3. Diversity performances like ECC, DG, and TARC & CCL are determined to confirm the MIMO antennas work qualities. The simulated and measured results of the proposed antenna have been observed.
