“…The antenna array has an ultra-wide operating range of 3.3-6 GHz (S 11 -6 dB) [13]. A dual-polarized MIMO antenna design operating in the sub-6 band with a band of 2.93 GHz (7.42-10.36) GHz at −10 dB with a return loss of −44 dB at resonance is required for applications requiring 5G phones [14].…”

The main challenges of designing an antenna for modern wireless communication are size reduction and mutual coupling. An ultra-wideband (UWB) multiple input multiple outputs (MIMO) antennae with four elements is suggested by this paper. Each element has two ports with dual-polarized patches to reduce the result of reciprocal coupling, increase the capacity, and keep a proper size. A circular geometric shape is in front of the patch of the proposed antenna to reduce the impact of mutual coupling. The CST STUDIO 2019 program simulates the single antenna element and MIMO antenna using four integrated elements, eight integrated ports, and an Fr-4 insulating layer in an area of (70 × 70) mm 2 . The MIMO antenna's operating frequency, which has a band of 2.85 (3.15-6) GHz at −10 dB, is 3.67 GHz while the operating frequency of a single antenna element, which has a band of 2.8 (3.1-5.9) GHz at −10 dB and a resonance return loss of 36 dB, is 3.64 GHz. The MIMO antennas obtained a diversity gain (DG) of about 10 with a good gain of about 8 dB while the envelope correlation coefficient (ECC) was equal to or less than 0.0001.
