In this article, a miniaturized reconfigurable 4-element ultra-wideband (UWB) multiple-input-multiple-output (MIMO) antenna is proposed to operate from 2.52 to 24 GHz, and studied using characteristics mode analysis (CMA). Initially, a 1-element antenna is designed and then extended to 4-element MIMO configuration. The MIMO antenna achieves design merits by orthogonally sorting fractal radiators for miniaturization, a Γ-shaped slot for band-notching and rotationally symmetric connected ground for isolation. CMA is explored to study the band-notched behavior effect in antenna, which shows two operating modes, NM-mode and NB-mode (NM: normal-mode, NB: Notched-mode). The modal metrics is discussed for both modes giving an insights on the bandwidth and radiation potentials. Four RF p-i-n diodes are mounted at the Γ-shaped slot orifice on each antennas, to control the band-notched operation. At OFFstate, the antenna is with wide-band-rejection from 3.7 to 8.87 GHz and at ON-state, it works in pure UWB mode. To demonstrate its feasibility, a fabricated antenna of size 24 mm Â 24 mm is experimented which are in good agreements with simulated results.

“…As shown in Figure 23 , the diversity performance was evaluated through the envelope channel coefficient (ECC) using the far-field calculation method [ 58 , 59 , 60 , 61 , 62 ] for better accuracy. During the evaluation, we considered gaussian for elevation and uniform for azimuth as the angular power density function.…”

A miniaturized four-element antenna of 20 mm × 20 mm with edge-to-edge distance of 4.9 mm between the array antennas operating from 4.6–8.6 GHz is investigated in this article. The antenna consists of 4 × integrated dipole driven elements, and complementary split ring resonator (CSRR) metacells are loaded on the both sides of each dipole arms. The loaded meta-couplers magnetically couple to dipole drivers, and the induced resonance effect improves the 10-dB impedance bandwidth (IBW) to 60.6%. To improvise the isolation between antenna elements, metallic vias are implemented that trap electromagnetic (EM)-surface waves to condense into the ground. So, the meta-couplers induce electromagnetic (EM)-propagation as surface wave trapments for radiation and decouple near-field condensed currents, acting as couplers/decouplers. The maximum isolation achieved is >−22.5 dB without any external decoupling network. The diversity parameters indicate good attributes in isotropic, indoor, and outdoor channel environments with an envelope correlation coefficient (ECC) < 0.165 and realized gain of 5.5 dBi with average radiation efficiency of 80–90% in the desired operating bands. An equivalent circuit model using lumped components is designed for the proposed four-element antenna. For validation, a prototype antenna is fabricated and measured to be implemented in 5G applications, which shows good correlation with the full-wave simulated results.
