Abstract

In this article, the designing and analysis of a compact novel dual-port multiple-input multiple-output (MIMO) printed antenna are investigated for 30 GHz mm-wave applications. The single antenna unit is having modified C-shaped radiator and an attached rectangular stub with an overall dimension of 10 × 7 × 0.8 mm³. The dual-element MIMO antenna is achieved by creating a back mirror of the single antenna element around the x-axis. This back mirror composition of the MIMO antenna elements is introducing the high level of inter-element isolation (> 20 dB). The proposed antenna prototype is built on a Roger RT/duriod substrate with a loss tangent (tanδ) of 0.0009 and a relative constant (ε_rsub) of 2.2. As a way to determine the capabilities of the proposed MIMO antenna, many diversity parameters are computed, including the envelope correlation coefficient (ECC < 0.05), diversity gain (DG > 9.99 dB), channel capacity loss (CCL < 0.2 bits/s/Hz), mean effective gain (MEG < − 3 dB), and total active reflection coefficient (TARC). The suggested MIMO antenna is appropriate for 5G new radio frequency bands under mm-wave communication as it has 8.36% impedance bandwidth across the frequency range of simulated (29.04–31.57 GHz)/measured (28.82–31.30 GHz). The antenna under consideration is constructed, and the simulated outcomes are verified by the measurement results.
