Multi-Band Rectangular Hybrid Antennas Loaded with Inter-Digital Structure Slot
Bibliographic record
Abstract
In this paper, two rectangular multi-band hybrid antennas are proposed. Modified Inter-digital structure slot is loaded on top of DRA to achieve multi-functional capability for sub 6 GHz wireless applications. The tri-band hybrid antenna with modified inter-digital structure resonates at 2.93 GHz, 3.26 GHz & 5.5 GHz and consequent Return Loss (RL) bandwidths are 40 MHz(2.91-2.95 GHz), 60 MHz (3.23-3.29 GHz) and 230 MHz (5.37-5.6 GHz) respectively. The proposed quad-band hybrid antenna resonates at 2.48 GHz, 2.84 GHz, 3.26 GHz and 5.5 GHz and resultant RL bandwidths are 40 MHz, 40 MHz, 60 MHz and 220 MHz respectively. The field analysis and parametric study of the proposed hybrid antennas are presented using Ansys-HFSS Electro-magnetic solver. The gains obtained for the proposed antennas are more than 4 dBi at all the resonances that have been occurred.

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.
