Compact microstrip-fed antenna for 2.4/3.5/5.2/5.8 GHz wireless communication systems
Bibliographic record
Abstract
A compact low-cost planar antenna is proposed to cover the WLAN frequency bands centered at 2.4, 5.2 and 5.8 GHz. It was observed that the resonant frequencies of the antenna can be easily adjusted. The return loss in the 5.2 to 5.8 GHz range is effectively controlled by using a strip to short out the surface current. The antenna shows a donut-shaped radiation pattern in the E-plane and an omnidirectional radiation pattern in the H-plane for both lower and upper WLAN frequency bands. Inserting an additional radiating element into the antenna geometry allows the antenna to operate in the WiMAX frequency band at 3.5 GHz, as well as the WLAN frequency bands. The housing effect of devices in the vicinity of antenna is also investigated, and it is observed that the orientation of the antenna to a nearby box is critical in maintaining the performance of the antenna.

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.
