Transmission Line Model of a Hertzian Dipole Antenna with FSS Superstrates and AMC Ground Plane to Extract Its Far-field Radiation Properties
Bibliographic record
Abstract
Highly reflective surfaces as antenna superstrates have applications in the gain enhancement [1]. These surfaces can be realized by different means using high permittivity or high permeability materials, or highly reflective frequency selective surfaces (FSSs) [1-6]. On the other hand, one can make these high-gain antenna designs low-profile, using artificial ground planes [5-6]. A full wave analysis of actual antennas, which will have truncated FSS superstrates and artificial magnetic conductor (AMC) ground plane will be time-consuming and will need a large amount of computer memory due to the metallic patches or different dielectric layers. The transmission line equivalent network (TEN) models have been successfully employed to extract far-field radiation properties of Hertzian dipoles over conventional ground planes (PEC) with superstrates [2-4]. It was proposed in [6] that TEN models can also be used in designing antennas with artificial ground planes. However, only full-wave analysis of a few antennas having ideal (lossless, angularand polarization-independent) reactive impedance surfaces and a truncated FSS superstrate was reported. In this paper, TEN models are used to obtain radiation properties of a Hertzian dipole with angular-dependent FSS superstrates and AMC ground planes. The results are compared with selected ideal cases.

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.
