A novel microwave omnidirectional antenna for wireless communications
Bibliographic record
Abstract
A novel microwave omnidirectional antenna is proposed in this paper for wireless communications. This antenna is constructed with cavity-restrained multi-stacked dielectric disks. Vertical polarized omnidirectional radiation patterns are obtained from radiative ring slots in the side wall of dielectric-metal cavities operating on TM/sub 01/spl delta// mode. High omnidirectional gain is realized with stacked cavities with multi-radiative slots. Ring slots between the adjacent cavities are used to enhance the excitation of the desired radiating mode in phase, which actually eliminates the feed network. A special technique is adopted for excitation of the antenna from coaxial line, with which very good matching is achieved. This type of antennas could be ideal for the base or center stations for wireless and indoor communications. Experimental results of a prototype of the antennas working at 12.6 GHz is given to demonstrate the great potentials for wireless applications.

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.
