Radiation pattern enhancement of microstrip patch antennas using a 2D photonic band gap structure
Bibliographic record
Abstract
Recently, there has been extensive research on the photonic band gap structures (PBG's) and their applications in the microstrip antennas and transmission lines. The PBG structures have the unique property of preventing the propagation of EM waves in certain directions for certain frequencies. The properties of these structures are defined by the shape, size, symmetry and, the constituent material. These periodic structures come in many shapes and forms. Some of these include drilled holes in the dielectric, patterns etched in the ground plane, and metallic patches placed around microstrip structures. The PBG structure studied in this paper consists of metallic patches with center vias connecting the patches to the ground plane. The properties of this 2D structure are studied using the Ansoft Ensemble simulator which is based on the method of moments (MOM). Two microstrip patch antenna using the PBG structure are designed and the effects of the PBG on the gain and radiation pattern are shown. It is observed that the radiation pattern of the patch antennas can be controlled by changing the parameters of the surrounding PBG structure.

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.
