Millimeter-Wave Low-Profile Continuous Transverse Stub Arrays With Novel Linear Source Generators
Bibliographic record
Abstract
This paper presents a new type of continuous transverse stub (CTS) antenna array with a novel linear source generator (LSG). The conventional multilayer parallel-plate waveguide (PPW) feed and pillbox structure are eliminated and replaced with a more compact partially corporate feed network. This helps to achieve a lower profile (or reduction of antenna layers) and high performance of broadband and high efficiency. For validation, two prototypes are demonstrated-one based on hollow waveguides operating at 34-41 GHz (Array-I) and the other based on substrate integrated waveguides operating at 24.5-29.5 GHz (Array-II). Both arrays contain eight radiation slots, fed from a single-layer PPW junction. The required quasi-transverse electromagnetic wave excitations are achieved by using the novel LSG of a jagged cavity structure. The detailed design methodology and analyses are provided in this paper. Measurements show that antenna efficiencies of over 83% and 82% with the peak gains of better than 27.6 and 20.6 dBi are achieved for Array-I and Array-II, respectively. These low-profile CTS designs are well suited for current and emerging millimeter-wave applications such as 5G and point-to-point communications.

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.
