Abstract
Abstract: In this paper a radiating element consisting of a modified circular patch is proposed for MIMO arrays for 5G millimeter-wave applications. The radiating elements in the proposed 2×2 MIMO antenna array are orthogonally configured relative to each other to mitigate mutual coupling that would otherwise degrade the performance of the MIMO system. The MIMO array was fabri-cated on Rogers RT/Duroid high frequency substrate with dielectric constant of 2.2, thickness of 0.8 mm and loss tangent of 0.0009. The individual antenna in the array has a measured impedance bandwidth of 1.6 GHz from 27.25 to 28.85 GHz for S11 ≤ −10 dB, and the MIMO array has a gain of 7.2 dBi at 28 GHz with inter radiator isolation of greater than 26 dB. The gain of the MIMO array was increased by introducing frequency selective surface (FSS) consisting of 7×7 array of unit cells comprising rectangular C-shaped resonators one embedded inside the other with a central criss-cross slotted patch. With the FSS the gain of the MIMO array increased to 7.6 dBi at 28 GHz. The radiation from the array is directional and perpendicular to the plain of the MIMO array. Owing to the low coupling between the radiating elements in the MIMO array its Envelope Correlation Coefficient (ECC) is less than 0.002 and Diversity Gain (DG) is better than 9.99 dB in the 5G oper-ating band centered at 28 GHz between 26.5 GHz and 29.5 GHz.
