Design of a Compact SWB High Gain Antenna Using a Fully PEC Reflector
Bibliographic record
Abstract
In this paper, a high-gain and low-profile super wideband (SWB) antenna is presented. The proposed design consists of an asymmetric coplanar waveguide (CPW)-fed modified Y-shaped monopole antenna. A parasitic patch in the ending of bowtieshaped leads to improve the impedance match performance. Therefore, a fully PEC reflector is included in order to enhance the gain by combining the output and the reflected waves in the boresight direction. An impedance bandwidth of 124% is obtained (4.2-18 GHz for VSWR less than 2) with a very compact size of$0.15\lambda_{0}\times 0.22\lambda_{0}\times 0.012\lambda_{0}$. Directional radiation patterns for the E and H-planes are achieved. The realized gain of the proposed antenna is enhanced by 3-6.5 dBi over the operating band, and the total efficiency is more than 85%. All these features make the proposed antenna a good candidate for RADAR and WLAN communications.

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.
