Graphene based terahertz MIMO antenna with machine learning regression for 6G communications.
Article in Scientific reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
This study introduces a compact, high-performance multiple-input multiple-output (MIMO) antenna engineered for 6G terahertz (THz) communication systems. The antenna is implemented on a polyimide substrate (dielectric constant εr = 3.5, loss tangent tanδ = 0.0027) with dimensions of 405 × 163.75 μm², providing a miniaturized footprint suitable for integrated wireless devices. The antenna exhibits multi-resonance operation at 3.752, 4.204, 4.652, 5.104, 5.548, 6.000, and 6.460 THz, providing corresponding bandwidths of 0.3348, 0.2634, 0.2389, 0.2289, 0.2158, 0.2063, and 0.2096 THz, ensuring wideband coverage suitable for high-data-rate applications. The antenna achieves a peak gain of 13.353 dB, outstanding isolation of − 34.044 dB, and high efficiency of 96.048%, highlighting its suitability for high-data-rate and low-interference 6G communications. Strong diversity performance is demonstrated through an ultra-low envelope correlation coefficient (ECC) of 0.00017856 and a near-ideal diversity gain (DG) of 9.99911, confirming the effectiveness of the proposed design for interference mitigation and channel reliability. CST Microwave Studio (MWS) simulations were employed to generate datasets for supervised regression machine learning to predict antenna gain. Random Forest Regression delivered superior predictive accuracy with MSE = 0.76%, MAE = 5.43%, RMSE = 8.72%, R² = 93.93%, and variance score = 95.12%, closely matching the simulated results. The integration of high-performance multi-band antenna design with regression-based machine learning demonstrates a reliable framework for rapid performance evaluation. The combination of compact geometry, wide multi-band operation, high gain, strong isolation, and machine learning-based predictive modeling positions the proposed antenna as a promising solution for high-data-rate and interference-resilient 6G THz communication networks.
