Abstract
The manuscript represents a novel superstrate metamaterial loaded microstrip patch antenna to achieve multiband frequency reconfigurability. The performance is observed for the frequency band of 4 to 8 GHz. Metamaterial property is enabled by engraving triangular-shaped split-ring resonators in the substrate. Frequency tunability is achieved based on the switching mechanism of three PIN diodes. Different materials are loaded in the split ring resonators like copper, distilled water, and seawater for the performance observation in terms of reflectance response, Bandwidth, gain and tunability. The design provides the reflectance response of −43.38 dB, Bandwidth of 220 MHz, and frequency tunability of 100 MHz. The proposed design is also giving the highest gain of 8.3 dB. The structure is fabricated using FR-4 to reduce the overall cost of the antenna, and it is tested using a vector network analyzer and anechoic chamber. Simulated results and fabricated ones are compared for reliability. The proposed design, with its flexible and reconfigurable capability, can be applicable in IoT applications.

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 it
