Abstract
A miniatured two-port wide-band MIMO antenna is presented in this work for use in 5G communications. The antenna measures 24 mm × 36 mm × 1.6 mm (0.2λ × 0.3λ × 0.0133λ) and developed on FR-4 dielectric. The MIMO design composed of up of a multi-slotted circular two-element radiating patch and an I-shaped defected ground plan. To create the required operating bands at 2.5 GHz, 3.8 GHz, and 4.9 GHz frequencies, the radiating patch is carved with a circle-shaped slot, a crescent-moon-shaped slot, and a rectangle slot in the ground. The designed antenna operates at 2.5 GHz (N38: 2.35–3.0 GHz), 3.8 GHz (N77/N78: 3.3–4.4 GHz), and 4.9 GHz (N79: 4.7–5.5 GHz) with respectable impedance matching. The usage of a rectangular stub with minor protrusions and slots increases the MIMO antenna's impedance and isolation performance of more than 15 dB. Moreover, the antenna offers omnidirectional patterns, stable gain and efficiency, envelop correlation coefficient (ECC) of lower than 0.00001, diversity gain of 10, mean effective gain of −3 dB across the functional bands. The findings demonstrate that the suggested architecture is a strong contender for 5G sub-6 GHz applications.
