1 · What the graph read from it

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.

2 · The registry

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

In this paper, a miniaturized 2 × 2 MIMO dual-wideband ground radiation antenna targeting Wi-Fi 6/6E/7 standards using 2.4 GHz, 5 GHz, and 6 GHz frequency bands with sufficient antenna performance was designed. The proposed antenna system contains four identical 4 mm × 6 mm antennas of the internal loop type and two identical 6 mm × 6 mm isolators containing lumped LC elements. This paper considers maximizing the impedance bandwidth using an advanced impedance control technique and isolation enhancement through T-shaped isolators. To achieve dual-wideband resonance, an impedance control method using LC parameter value control is employed by utilizing the coupling between the ground plane, the voltage source, the feed loop, and the radiation loop in each radiation band. The operating principle of the T-shaped isolator was proposed using the scattering matrix and impedance matching. Simulated results showed that the proposed antenna can cover 96 MHz at the 2.4 GHz band and 2,232 MHz at both the 5 GHz and 6 GHz bands with an impedance bandwidth of -10 dB and isolation performance of less than - 20 dB across all frequency bands. Average measured efficiencies of 52%, 74%, and 80% were obtained for the corresponding operating bands.
