Investigation of MIMO Antenna Design for Sub-6 GHz 5G (N77/N78 and N79) Applications

This paper suggests the usage of a chopped moon-shaped monopole MIMO antenna for 5G Sub-6 GHz N77/N78 and N79 spectrum applications. The intended antenna is made of two modified moon-shaped monopoles with parasitic rectangular-shaped elements. A Co-planar Waveguide (CPW) feed is employed at the substrate's top side when using microstrip feeding, and it offers good impedance matching for desired 5G band applications. The functioning band of the design is 2.4 GHz (3.1- 5.5 GHz) and the isolation is below 18 dB. This 5G antenna's performance has been analyzed, taking into account the conclusion of varying the antenna's geometric constraints. Throughout the entire operating band, good impedance matching, acceptable radiation pattern, and gain are observed.
