“…The MIMO antenna parameters, such as Envelope Correlation Coefficient (ECC), Diversity Gain (DG), and Mean Effective Gain (MEG), are investigated. ECC and DG values are evaluated from far-field equations ( 1) and ( 2) for better accuracy [21], and MEG is also a very important parameter; at each port, it can be evaluated from the S-parameter equation (3) as follows [30].…”

A compact dual-feed multiple-input multiple-output (MIMO) antenna is designed for sub-6 GHz 5G applications with isolation enhancement. The proposed dual-polarized MIMO antenna formed by each patch uses two inset-feed lines placed orthogonal to each other with symmetric conditions, which excite each port to resonate at the same frequency (3.65 GHz). The stub is identified diagonally based on plated through-hole technology between orthogonal ports. The structure employs a half mode and maintains minimum interport isolation (≤ −12 dB) of each patch, followed by another patch to form an 8-element miniaturized MIMO antenna. High isolation (≤ −15 dB) is achieved with the help of a decoupling structure placed between the antennas in the ground plane. Measurements of a fabricated prototype validate the simulation results. The diversity performances of MIMO antenna parameters like envelope correlation coefficient (ECC), diversity gain (DG), and Mean Effective Gain (MEG) are also found within acceptable ranges.

A compact size UWB circularly polarized (CP) dual-port MIMO antenna is designed for Ku/K band applications. The proposed antenna contains a revised circle-shaped slot from the radiation patch on the front-side and a stepped-feed line on the back-side of the substrate. The orthogonal position of the antenna ports allows us to produce isolation of more than 30 dB and has a (−10 dB) impedance bandwidth of 68% (14.3-29.3 GHz) at two resonant frequencies 15.6 GHz and 24.7 GHz, respectively. 3 dB ARBW in the operating bands is 14.6% and 6.7%, respectively. The total size of the MIMO antenna is 0.1λ × 0.05λ × 0.003λ mm 3 at a lower frequency. Diversity characteristics like ECC, DG, TARC, & CCL are determined to confirm the MIMO antenna's work qualities. Ringing resonating frequencies are observed at lower operating bands and are responsible for gain degradation. The proposed antenna has excellent characteristics for satellite and NASA's Tracking Data Relay Satellite application.

Small footprint of the multi-input-multi-output (MIMO) antenna is extremely desirable for space-constrained ultra-wideband (UWB) communication systems. Compact MIMO antennas with improved isolation and wide operating bandwidth are the significant subject of the work. Therefore, this paper presents a miniaturized four-port polarization diversity UWB-MIMO antenna operating in the frequency range of 3.1-12 GHz with band-notched characteristics. Four octagon-shaped radiating elements with a common ground are placed orthogonal to each other for good isolation. Band rejection features between 4.5 and 5.5 GHz were achieved by including an open-ended slot at the upper edge of the octagonal-shaped antenna. The MIMO antenna was etched on a low-cost 32.3 × 32.3 × 0.8 mm 3 FR-4 dielectric substrate. The antenna radiates in a quasi-omnidirectional pattern on the H-plane throughout the operational bandwidth, with higher than 15 dB isolation, low envelope correlation, and high antenna gain. As a result, this antenna is well suited for diverse applications and portable devices.
