5G wireless communication microstrip patch antenna array design with MIMO

The development of the digital environment seeks the best and more efficient communication. Recent researchers are looking forward to 5G wireless communication. But this wireless communication requires a more efficient antenna design to achieve their aspects. Therefore, the proposed work is concentrating to design a high antenna for 5G wireless communication. In this work, the circular array microstrip patch antenna (MPA) design is proposed for the 5G wireless communication and the millimeter wave is utilized for this communication system to enhance the coverage area. Here, the Multi Input Multi Output feeding technique is utilized to enhance the performance of the proposed antenna design. The resonance frequency of the proposed antenna is taken as 35 GHz and RT-Duroid 5880 material is utilized for the substrate. It has a 2.2 dielectric constant value and the thickness is 0.5 mm. The simulation analysis is obtained the gain as 8.8 dB and return loss as -41.9 dB. Also, two MPA designs such as single element MPA and 2 × 2 rectangular array MPA are designed to validate the proposed antenna design. The designed microstrip patch antennas are compared by utilizing the parameters such as Gain, Return loss, VSWR, Mutual coupling, Bandwidth, and radiation efficiency. The comparative analysis proved that the proposed circular array MPA design is preferable for the 5G wireless communication system compared to the other two designs such as single element MPA and 2 × 2 rectangular array MPA.
