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

This work presents a novel compact rectenna design for wireless power transfer (WPT) at 3.5 GHz, targeting 5G-enabled low-power IoT devices. The proposed system integrates an optimized patch antenna with a Schottky diode-based rectifier, enabling efficient RF-to-DC energy conversion in a compact footprint. A systematic co-design approach combining electromagnetic simulations and circuit-level modeling was employed to optimize impedance matching and maximize conversion efficiency. A parametric study of the load resistance revealed an optimal value of 5 kΩ, achieving peak power transfer efficiency under realistic operating conditions. The rectenna prototype was fabricated and experimentally characterized, confirming the simulation results and demonstrating a maximum DC output voltage of 0.91 V at an input power level of 0 dBm. The proposed design offers a practical, reproducible, and high-performance solution for 5G wireless energy harvesting, addressing the challenges of compactness, efficiency, and reliability for next-generation IoT applications.
