Design of half elliptical ring monopole antennas with elliptical slot in ground plane for future UWB applications
Bibliographic record
Abstract
Abstract In this letter, a microstrip fed ultra‐wideband (UWB) antenna with different band rejection techniques is presented. The designed antennas consist of a defected ground plane with an elliptical slot and elliptical shaped radiating element. The measured and calculated impedance bandwidth of the proposed antenna ranges from 3 to 14 GHz for a return loss (S 11 ) less than −10 dB. Also, it has a relatively stable radiation patterns over its whole frequency band of interest. Two different techniques have been proposed to achieve band‐notch characteristic in the 5.0‐ to 6.0‐GHz wireless local area network frequency band. The first one uses L‐shaped parasitic strip into the radiating patch, whereas the other one uses two rectangular slits cut away from the ground plane creating defected ground structure. The proposed antenna is considered a good candidate for UWB applications. © 2011 Wiley Periodicals, Inc.

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.
