Abstract

fetched live from OpenAlex

In this paper, the directivity of microstrip patch antennas with double-layer superstrate is investigated. Two dielectric superstrate layers, each a quarter wavelength in thickness and separated by an air gap, are introduced above the microstrip patch, separated by another air gap. The parameters of these layers are used as key controllers of the directivity enhancement. Numerical results indicate that the directivity increases significantly even with moderate superstrate dielectric constants when the double-superstrate configuration (DSC) is used. To demonstrate how the layers affect the directivity, an infinite dielectric model is first used. Then the effect of the superstrate transverse dimensions is studied by means of a finite dielectric model. The directivity variations with respect to frequency are compared for different superstrate surface areas. This work leads to the conclusion that modification of the superstrate transverse dimensions can optimize both directivity and bandwidth. The experimental investigations of DSC are also provided to support the simulation results.

Teacher imitation

Not 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.
