A Novel Array antenna fed by CPW for an EHF in-building WLAN system
Bibliographic record
Abstract
This paper presents novel printed array antennas fed by CPW (coplanar waveguide) configuration with a feed line on single layer for the EHF band around a center frequency of 30 GHz. This type of coupling is advantageous when applied to millimeter wave monolithic phased arrays. A unique feed design eliminates the competition for surface space between the antenna elements and the feed network Besides, the ground plane shields the antenna half-space from spurious radiation emitted by feed lines and active devices. The single and array antennas are designed on a high dielectric constant substrate (/spl epsiv/r = 9.9), which demonstrates the feasibility of integration of such an antenna structure into monolithic circuits. The array antenna is the key component in a switched beam antenna system used in a prototype broadband wireless LAN system operating at up to 160 Mbit/s. Details of the overall system, which is intended for in building communication, is also presented.

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.
