The current invention demonstrates a novel four element compact multi-band and ultra wideband MIMO (multiple-input multiple-output) antenna. The suggested antenna is intended for use in the 6G mmWave band applications. It operates in four operational bands, the first of which has a frequency of 22.23 GHz for the stated band of 7-24GHz. The operational frequency of the second band is 34 GHz in the 32GHz band, while that of the third band is 43.69GHz in the upper 40GHz band. The fourth band’s operational frequency in the 50GHz range, which is 53.38 GHz. The exhibited 6G antenna measures 25 mm × 28 mm × 0.508 mm and is made of low-loss dielectric material Rogers RT/Duriod 5880 (tm) which has a dielectric loss tangent of 0.0009 and relative permittivity of 2.2.
Prospective bands for the upcoming version of wireless networks include those between 100 GHz and 3 THz. In addition, new ideas and technological advancements in circuits, signal processing, devices, and systems will open up new applications at these frequencies. Global Wi-Fi use at frequencies between 252 GHz and 325 GHz is going to create the first global communication standard for the 250–350 GHz frequency range.
The mm-wave MIMO antenna is a viable option for virtual reality services and the streaming of huge video material, however as of yet, 5G wireless technology-specific standards have not been developed or put into practice. Many scholars have begun to bring the standard's foundation, nonetheless. Few mm-wave MIMO antennas are therefore now available. There was a proposal for a MIMO antenna that used two linear arrays, each array having four cylindrical dielectric resonator antennas operating at 30 GHz. Beam tilting was achieved by means of a passive microstrip feed network.
