A New Aperture Antenna Using Substrate Integrated Waveguide Corrugated Structures for 5G Applications
Bibliographic record
Abstract
In this letter, two new high-gain aperture antennas are presented using substrate integrated waveguide (SIW) corrugated structures. The antenna is excited by a transmission line at the bottom layer. Power is coupled to the patch through a cavity in the middle layer. Due to constructive superposition of the electric field by the grooves and patch, a relatively high-gain and narrow radiation pattern is achieved that depends on the number of grooves. In the proposed structure, three layers of boards for fabricating a resonant transmission line and specific SIW structures are employed instead of a waveguide feeder and grooves on a metallic plate as in conventional corrugated antennas. This technique removes the need to use a metallic layer and thus reduces the weight of the antenna structure. Two samples with two and four grooves have been designed, fabricated, and tested for 5G applications to show the validity of this approach. The results show that these grooves increase the gain of the antenna significantly.

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.
