3-D-printed X/Ku-band High-gain Integrated Lens MIMO Antenna Using CPW-fed Magnetoelectric dipoles
Bibliographic record
Abstract
A four-element high-gain multiple-input multiple-output (MIMO) antenna array covering X and Ku bands is presented that utilizes three-dimensional (3-D)-printed integrated lens antenna (ILA) as the MIMO element. The ILA uses a dielectric-embedded magnetoelectric (ME) dipole as the radiating element to obtain antenna miniaturization and wide impedance bandwidth (IBW). Full-wave simulations exhibits a total active reflection coefficient, |TARC| and |S11|$\leq-10$dB, for 75% bandwidth while minimum isolation is above 25 dB. The peak gain is $\sim$10.9 dBi while the envelope correlation coefficient (ECC) is $\leq$0.003. The measured element prototype exhibits IBW of 75% and maximum measured realized gain of 10.7 dBi wherein the footprint at lowest operating wavelength is 0.69$\lambda^{2}$.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
