Design and Optimization of a Miniaturized Meander Antenna for 2.45 GHz Biomedical Implants
Bibliographic record
Abstract
This research showcases a novel ultra-compact antenna for biomedical implants operating at the 2.45 GHz Industrial, Scientific, and Medical (ISM) band. It features a small footprint of 1.27 mm<sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sup>, measuring <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$3.3 \times 3.3 \times 0.12 \text{mm}^{3}$</tex>, achieved through a resonator patch with a meandered design on a high-permittivity substrate for efficient miniaturization. Testing the antenna within a phantom box that contains muscle, fat, and skin shows a maximum gain of −23.6 dB at 2.45 GHz, highlighting its satisfactory performance given its small size. The antenna also exhibits omnidirectional radiation patterns. Additionally, the antenna's specific absorption rate (SAR) analysis confirms its safety. These findings underscore the antenna's practicality, versatility, and potential for integration into various biomedical applications.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
