Wide-Beamwidth Unilateral Dielectric Resonator Antenna Using Higher-Order Mode
Bibliographic record
Abstract
For the first time, a unilateral rectangular dielectric resonator (DR) antenna (DRA) is designed using two DR modes, namely the fundamental T E <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">δ11</sub> <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">x</sup> mode and higher-order T E <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2δ1</sub> <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">y</sup> mode. The former and latter provide the broadside and quasi-omnidirectional radiation patterns, respectively. By combining the radiation fields of the two resonant modes, unilateral radiation with wide 3 dB beamwidths can be obtained. For demonstration, a unilateral rectangular DRA was designed in 2.4 GHz WLAN band. Across the WLAN band, the DRA has a measured front-to-back ratio (FTBR) of higher than 15 dB. It is found that the measured maximum FTBR of the DRA is 36.6 dB, whereas the measured 3 dB beamwidths of the two principal radiation planes are both wider than 174°.

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.
