A Compact Slot-Loaded Quarter-Wave Patch with Resonance Frequency Formulation for Wi-Fi and Wi-Max Applications
Bibliographic record
Abstract
A single layer and compact dual band antenna is presented for the Wi-Fi and Wi-MAX applications. A shorted quarter-wave patch is used to reduce the size. Further, a slot is cut in the non-radiating edge to create additional resonance. The impedance matching at this second resonance is enhanced by cutting a slot in the radiating edge. An equivalent circuit is suggested to explain the behavior of the proposed dual-band antenna. It is confirmed from the numerical calculation that the resonance frequency depends on the lengths l3 and l9 of the structure. The derived formulas provide the value of lengths l3 and l9 according to the user's desired frequency. The dimensions of the antenna are optimized using a commercial full-wave simulator. The concept is verified through measurements. The final design exhibits resonances at 2.44 and 3.33 GHz with a gain of 3.1 and 5.3 dBi, respectively. The cross-pol radiation levels are below 20 dB along the broadside direction.

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.
