Integrated Multiport Leaky-Wave Antenna Multiplexer/Demultiplexer System for Millimeter-Wave Communication
Bibliographic record
Abstract
A novel application of leaky-wave antennas (LWAs) as multiplexers/demultiplexers is proposed and experimentally demonstrated in the millimeter-waveband at 60 GHz. The first application is demultiplexing of an oblique-incident free-space wideband plane wave into 2N channels using N LWAs with different beam-scanning laws. The second application is N-channel multiplexing and demultiplexing using N pairs of identical LWAs in each other's far-field, where each LWA pair is designed such that the broadside frequency is the center frequency of its respective channel. The Friis transmission equation is first used to analytically demonstrate the two applications. The LWAs are then implemented using reflection-canceling slot pairs using substrate integrated waveguide technology. The two applications are demonstrated in full-wave simulations and experimentally by conducting horn-to-LWA and LWA-to-LWA transmission measurements. The proposed LWAs provide a simple, compact, and high-efficiency multiplexing/demultiplexing solution with high-integration capability with other circuitry. Compared with conventional multiplexers, LWAs do not require matching networks and can be directly scaled to higher frequencies using the same architecture.

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.
