Path loss characterization of a compact dual-band mmWave antenna in urban microenvironments.
Article in PloS one, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 work presents a compact dual-band millimeter wave (mmWave) antenna that operates at 17-27 GHz and 36-43 GHz, with resonance frequencies centred at 21.1 GHz and 38.3 GHz, respectively. The multiple embedded arc-shaped mmWave antenna geometry provides compact, effective dual-band operation. The concentric arcs of the antenna structure are effectively optimized to produce a dual band of operation with good impedance matching. The resulting antenna has gain of 4.8 dBi at 26 GHz and 6.1 dBi at 37 GHz frequencies. The developed antenna is intended for widespread usage in satellite and 5G networks. Despite providing significant bandwidth for 5G and other next-generation communication systems, mmWave frequencies are susceptible to path loss, particularly in congested urban areas. This study further investigates the performance of the designed dual-band mmWave antennas in various urban environments. Both Line-of-Sight (LOS) and Non-Line-of-Sight (NLOS) scenarios are considered to capture realistic deployment conditions. To accurately model propagation behaviour, the analysis incorporates the ABG and CI path-loss models, which comprehensively account for environmental factors such as shadowing, diffraction, and precipitation.
