Abstract
This paper presents a compact and highly isolated two-port leadless pacemaker duplex antenna, operating at 915 MHz (when Port-1 is active) and 1300 MHz (when Port-2 is active). For compactness, a high-dielectric substrate, shorting pins, and capacitive slots are used. A high isolation level between the transmit and receive units is obtained by etching rectangular slots on the ground plane and introducing a series of vias between them. Consequently, the designed antenna has a compact size of π × 4.482× 0.13 = 8.19 mm3 and a high isolation level of 34.6 dB. It maintains a suitable gain of -25.6 dBi at 915 MHz (when Port-1 is active) and -19.7 dBi at 1300 MHz (when Port-2 is active). The suggested design is suitable for wireless leadless pacemakers, thanks to its compact design, highly isolated uplink and downlink wireless channels, and high gains.

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.
