Self-diplexing Antenna Operating at Sub-6 GHz and Millimeter-wave Frequency Bands
Bibliographic record
Abstract
A low-profile self-diplexing antenna supporting sub-6 GHz and mm-wave frequencies is introduced for the first time. The design process starts with cutting a Substrate Integrated Waveguide (SIW) cavity into two equal parts. One part is taken into consideration for the proposed antenna in a way that a small part of the cavity is selected for mm-wave operation (28 GHz), and the rest is assigned for microwave operation (4.8 GHz). A capacitive slot brings the microwave frequency to the desired band (4.8 GHz). The mutual coupling among the ports is less than -30 dB and the measured gains show 5.3 and 8 dBi for low and high bands, respectively. It should be mentioned that independence of frequencies is another advantage of the proposed structure. Therefore, such an antenna is a suitable alternative for traditional dual-band antennas.

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.
