Ultra‐compact end‐loaded planar dipole antenna for ultra‐wideband radar and communication applications
Bibliographic record
Abstract
A planar dipole antenna is loaded with LC‐tank resonators and chip resistors presented for ultra‐wideband (UWB) radar and communication systems. Each staircase rectangular arm of the proposed planar dipole is loaded with an open complementary double concentric split‐hexagonal‐ring resonator (LC‐tank) and a pair of chip resistors at the end for bandwidth enhancement, whereas a broadband microstrip to parallel‐plate transformer (or balun) is applied as the feeding structure of the antenna to provide impedance matching as well as balanced–unbalanced transition. The measurement results show that the proposed antenna operates over a frequency bandwidth of 0.64–3.8 GHz with S 11 < −15 dB and exhibits highly directive radiation patterns for the first 100% of the operating bandwidth (0.64–2 GHz) with gains in the range 2.2–4.2 dBi.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
