Coupling Reduction in Two by Two MIMO Vivaldi Antennas For Full Duplex Applications
Bibliographic record
Abstract
In this paper, a two by two Multiple Input Multiple Output (MIMO) Vivaldi antenna has been designed, simulated, fabricated, tested and results compared. The antenna is designed to operate at 3.5 GHz with a bandwidth of $700 \mathrm{MHz}(20 \%)$. The proposed antenna has a gain of approximately 8dB. High isolation up to 70 dB between transmit and receive antennas is achieved by using cross polarization and spatial separation between antennas. Two horizontally polarized (HP) antennas are used for transmitting and two vertically polarized (VP) antennas are used for receiving. The antenna structure is simple and easy to fabricate. The proposed antenna is an excellent candidate for full duplex (FD) and fifth generation (5G) applications.

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.
