High Gain Wideband Log-Periodic Antenna with Directors and Perforation for 5G Application
Bibliographic record
Abstract
Three configurations of substrate integrated printed log-periodic dipole array (PLPDA) antenna are presented. The antenna is designed at the ka-band for 5G applications. The antennas provide a peak gain of 12-14.5dBi with a bandwidth of about 59% (21-37GHz). First configuration, LPDA antenna backed by a flat ground, is proposed to reduce the back radiation and to improve the gain. Second configuration, directors are added to improve the gain (about 2.5 dBi) and reduce the back lobe further, but the return loss is increased. In the third configuration, the substrate is perforated to decrease the return loss. All of these proposed configurations of the substrate integrated printed LPDA antenna maintain fantastic front to back lobe ratio with low cross-polarization for the entire frequency 5G band.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
