A 5G Enabled Shared-Aperture, Dual-Band, in-Rim Antenna System for Wireless Handsets
Bibliographic record
Abstract
In this work, we present a shared aperture (SA), dual-band in metal-rim antenna system targeting the sub-6GHz and millimeter-wave (mm-wave) bands of the 5G wireless standard. The antenna system consists of a SA cactus-shaped slot engraved on the side of standard mobile terminal rim that hosts a microwave radiating structure covering the sub-6 GHz bands as well as a 4-element slot based connected antenna array (SB-CAA) covering the mm-wave bands. This provides a compact sized solution for multiband operation within these bands. The CAA has beam forming capabilities where the beam can be steered between +/-30 degrees with acceptable gain and side lobe levels (SLL). A single 4-element slot based in-rim SB-CAA is also proposed that covered more than 6 GHz of frequency bandwidth (25.5–32 GHz) with a total efficiency exceeding 85% and realized averaged gain of 8.2 dBi over the bands covered. The SA cactus antenna structure had a bandwidth exceeding 3.5 GHz with total efficiency exceeding 75% and an average realized gain of 8 dBi between 26.5 – 30 GHz. For the microwave band covered (3.45-3.56 GHz) by this SA cactus antenna, a bandwidth of 140 MHz, efficiency of 90% with 2.5 dBi of measured gain were achieved.

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.
