A Dual Reconfigurable Printed Antenna: Design Concept and Experimental Realization
Bibliographic record
Abstract
In this article, we demonstrate the design concept and experimental realization of a dual reconfigurable printed antenna. A single coplanar waveguide (CPW)-fed printed monopole antenna can provide a reconfigurable ultrawideband (UWB)-notched or narrow-band (NB) response, depending on the status of the switches and the position of the split ring resonators (SRRs) in the CPW feed region of the antenna. The rectilinear movement of the superstrate, printed with various pairs of SRRs of differing dimensions, loaded in the feed region of the antenna, provides the reconfigurable functionalities. The position of the superstrate is controlled by a commercial servo motor programmed by a microcontroller. The antenna, along with the additional accessories required to actuate the mechanical movement, are fabricated and characterized using impedance and radiation pattern measurements. The measured results for both reconfigurable cases provide a good correspondence with the simulated results and the theoretical estimation. The proposed antenna can be used as a reconfigurable communicating antenna module of the cognitive radio (CR) system.

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.
