Abstract

Objectives: In order to simultaneously operate several system services, minimise attenuation, and reduce atmospheric absorption at the mm-wave spectrum, design of 5G antenna systems with enhanced bandwidth and gain is very crucial. MIMO antennas are therefore essential in addressing the shortcomings of the current designs. An integrated 5G MIMO antenna system using mm-wave and LTE is proposed in this work. Methods: The suggested design includes LTE MIMO antenna with two elements and 5G MIMO system four elements including circular as well as rectangular ground plane faults. The suggested structure is created on a Rogers RO4350B substrate for its excellent frequency performance, low dielectric loss, good thermal conductivity, and high impedance stability. The geometrical size and dimensions of the substrate used is 75 mm 110 mm 0.76 mm.The proposed structure operates between 5.6 and 6.5 GHz and 26 and 30 GHz (5G mm-wave). Therefore, 5.9GHz and 27.5GHz are the resonance frequencies used in this work. Findings: CST Microwave Studio is used to model and simulate the proposed system. The LTE and 5G mm-wave antennas both achieved maximum gain of 9.9 and 9.7 dB at 27.5 GHz and 4.1 and 3.9 dB at 5.9 GHz, respectively. Novelty: Additionally, the investigation of the MIMO performance metrics reveals high field correlation performance across the operating bands as well as positive attributes. Performance parameters like Gain, reflection coefficient, radiation pattern, and envelope correlation coefficient confirms that the proposed method complies with the international standards. Therefore, it is clear that the suggested integrated MIMO antenna arrangement could be a competitor for future communication applications.
