Estimation of Antenna Effect on Ultra-Wideband Pulse Shape in Transmission and Reception
Bibliographic record
Abstract
This paper presents an analysis of the antenna effect on ultra-wideband (UWB) pulse shape in transmission and reception. This analysis consists of a derivation of the impulse response for frequently used UWB antennas like the ridged horn, transverse electromagnetic horn, and bicone in the transmitting and receiving modes. An analytical/semianalytical expression for the received pulse has been derived. Frequency-limited gain of the transmitting and receiving antennas has been accounted for in the estimation of the received pulse. To demonstrate the antenna effect on a UWB pulse, various antenna combinations have been considered to transmit and receive different Gaussian pulses. A combination of transmitting and receiving antennas has been proposed for faithful reception of the transmitted pulse. This paper also studies the pulse shape and amplitude due to oblique incidence of the pulse on a receiving antenna. Measurements have been presented to support the proposed analysis, and they show good agreement with the estimated received pulses.

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.
