A Compact Dual Circularly Polarized MIMO Antenna with Controlled Slots for 5G Wireless Applications Across mm-Wave Spectrum
Bibliographic record
Abstract
This work presents a two-port circularly polarized multiple inputs multiple outputs (MIMO) antenna proposed for 5G mm-wave applications. This antenna consists of four low profiles slotted compact circular microstrip patch antenna with a partial ground and parasitic element for signal exchange in 5G spectra at the mm-wave range. The antenna operates between 27.2 and 28.35 GHz. A Roger RT5880 dielectric substrate measuring a compact dimension of 45.6 × 14.7 × 0.508 mm3, is used to etch the slotted antenna. The patch’s cross slots are designed to improve the targeted performance metrics including a wider bandwidth and better antenna impedance matching. At the resonance frequency of 27.7 GHz, the antenna showcases a gain of 4.43dB and an impressive return-loss of -15.6 dB. Coaxial feeding is employed for its operation. The MIMO antenna array is designed to deliver high performance with an average realized gain and radiation efficiency of 9.0 dB and 90%, respectively. It has a large bandwidth of 1.15 GHz, high gain, and directivity make it a promising candidate for 5G mm-wave GHz band applications.

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.
