Abstract
A compact and low-profile antenna for global navigation satellite systems (GNSSs), with particular optimization for triband Global Positioning System (GPS) coverage, is presented. A dual-band antenna is developed with the use of metamaterial-based electromagnetic bandgap structures (MTM-EBGs) that covers GPS L1, L2, and L5 bands and a majority of the GNSS spectrum. The patch antenna is fabricated on two sides of a single substrate sheet above a ground plane, with a 3-D printed polylactic acid (PLA) substrate spacer for simple fabrication. The antenna is fed by a wideband and planar feed network below the ground plane, and simulation and measurement results show good performance in terms of matching, gain, pattern shape, and axial ratio, demonstrating that this antenna is an excellent candidate for use with modern high-accuracy multiband and multisystem GPS/GNSS receivers.

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 it
