Miniaturized Parasitic Loaded High-Isolation MIMO Antenna for 5G Applications.

In this paper, a multiple-input-multiple-output (MIMO) antenna is reported for 5G frequency range-2 (FR-2), 28 GHz bands. The MIMO antenna is developed in multiple iterations, including single-element design, cross-polarization reduction, and mutual coupling reduction. Initially, a single-element coplanar edge feed rectangular patch antenna is designed and the E-plane cross-polarization is reduced by -13 dB by trimming the forward corners of the patch.
