A compact wide-dual-band antenna for bluetooth and wireless LAN applications
Bibliographic record
Abstract
A compact, wide-dual-band antenna is designed to satisfy 2.4-2.5 GHz and 5.0-6.0 GHz Bluetooth and wireless LAN applications. The antenna is composed of a rectangular dielectric resonator (DR), a foam former and a grounded inverted-L conductor plate with L-shaped slot. The first band with bandwidth 120 MHz is derived from the inverted-L antenna mode. The bandwidth of the second band is over 1 GHz, which is generated by two hybrid modes that are very close to each other. These modes are produced by the DRA and parasitic plate. The wide bandwidth and dual-band required for different Bluetooth and wireless LAN applications are readily achieved using the proposed antenna structure. Radiation patterns give omni-directional coverage in the azimuth plane. Thus this antenna satisfies simultaneously almost all the Bluetooth and wireless LAN application needs at different frequencies. The design is surface mountable and can be realized by LTCC technologies to obtain low cost and light weight.

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.
