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 paper introduces a novel design and development of a compact circularly polarized antenna operating at two distinct frequency bands, 2.5 GHz and 6 GHz. The innovation lies in using a modified circular patch and a uniquely designed feeding element, which optimize circular polarization performance while maintaining a low-profile form factor. Fabricated on an FR4 substrate with an overall thickness of 1.6 mm and dimensions of 62 mm × 62 mm × 1.6 mm, corresponding to approximately 0.5167λ × 0.5167λ × 0.0133λ at 2.5 GHz, the antenna achieves a compact configuration well-suited for space-constrained applications. Extensive simulations and measurements show close agreement, with axial ratios below 3 dB across both operational bands, ensuring effective circular polarization. The antenna achieves peak gains of 1.8 dBi at 2.5 GHz and 3.8 dBi at 6 GHz, highlighting its ability to combine compactness, dual-band functionality, and strong radiation characteristics. This proposed design provides a groundbreaking solution for Industrial, Scientific, and Medical (ISM) and Vehicle-to-Everything (V2X) communication systems, addressing the increasing demand for efficient, dual-band, and space-saving wireless communication solutions.
