Compact Omnidirectional Millimeter-Wave Antenna Array Fed in Series by a Novel Feed Network
Bibliographic record
Abstract
In this article, a novel substrate integrated waveguide power divider is proposed to feed antenna array elements in series. This feed network inherently provides uniform output power to eight quadrupole antennas. More importantly, it leads to a compact configuration since the feed network can be integrated inside the elements without increasing the array size. Its design procedure is first discussed. Next, the series feed network was used to feed a novel compact omnidirectional antenna array. Targeting the fifth-generation (5G) 26 GHz millimeter-wave (mm-wave) band, the simulated results showed that the proposed array exhibits a broad impedance bandwidth of 4.15 GHz and a high gain of 13.6 dBi. A prototype was fabricated and measured, exhibiting a measured impedance bandwidth of 6.72 GHz and a gain of 12.3 dBi. Its attractive features indicate that the proposed antenna array is well suitable for millimeter-wave wireless communication systems.

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.
