Isolation Enhancement of Ultra Wideband THz MIMO Antenna Using DGS

With advancements in communication applications, the antenna has been modified accordingly. One of the recent advancements in antennas is terahertz technology. Unlike other lower frequency bands, terahertz waves are nonionizing, comparatively health friendly offering a safe alternative for various applications for futuristic 6 G technologies. Patch antennas are becoming increasingly popular these days because of their small size, easy operation, and manufacturability. The presented design discusses a modified rounded rectangular patch terahertz antenna. The designs are generated by means of a high-frequency structure simulator tool; an overview of the evolution of the antenna element can be found. In the operating range of 2.1 to 12.1 THz, an operating bandwidth of 10 THz is obtained. A deliberate effort is made to assess and analyze its performance in compliance with MIMO (Multiple Input and Multiple Output) Configuration. The work in the paper paves the way for improvement in the related design and the extension of the MIMO capability of the proposed design with different orientations.
