Ambient RF Energy Harvesting for Dual-Band frequencies below 6 GHz
Bibliographic record
Abstract
In order to boost energy that could be exploited, dual or multi-band channels are needed to scavenge and harvest ambient RF energy. In this paper, a dual-band RF energy harvester is designed to operate in dual-band frequencies below 6 GHz. The signal received is harvested using a Schottky diode HSMS 2850. The circuit is optimized for low input power level using a Harmonic balance simulator. At the design phase, different dual-band frequencies are tested to show the flexibility of the proposed topology. Different methods of impedance matching have been investigated. A variety of Schottky diode implementation have been considered. The design is optimized to cover the two bands around 2.45 and 5.2 GHz. in the measurement, a shift in the dual-band to 1.95-4.8 GHz is observed. The two bands have been setup to measure their output voltage are 2-4.8 GHz. At2 GHz a maximum output voltage measured is 1.970 V at 24 dBm of the input power. For 4.8 GHz, a maximum output measured is 1.784 V at 24 dBm.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
