A Compact End-Fire Slotted SIW Antenna Array for 5G Mobile Handset
Bibliographic record
Abstract
This paper presents a 28-GHz slotted substrate integrated waveguide (SIW) antenna with end-fire radiation pattern for future 5G mobile handset. A pair of transverse slots is used in the broad faces to suppress back lobe radiation. The simulated 10-dB return loss bandwidth of the proposed SIW antenna is 26.9 GHz to 29.8 GHz. The proposed antenna achieves HPBW of 144.9° and gain of 5 dB with 98.8 % radiation efficiency. In comparison with open ended SIW front to back radiation ratio is increased up to 40 dB in this antenna. In order to achieve full spherical coverage, two beam steerable 4×1 subarrays could be employed in the top and bottom edges of the handset. The compactness, low cost and good performance of the proposed antenna make it an appropriate choice for the future 5G mobile handset.

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.
