PROJECT TITLE :

Antenna Current Optimization for Lossy Media With Near-Field Constraints

ABSTRACT:

Optimization of the present distribution is used to analyze how little antennas are plagued by amplitude constraints on the close to field and by lossy background media. The optimal antenna current that minimizes the stored energy, for a prescribed radiated field in an exceedingly given direction, and with limited near field in a very set of control points, is formulated as a convex optimization drawback. The analysis is additionally extended to antennas in lossy media by employing a frequency-spinoff approximation of the stored energy. The results recommend that many basic antenna issues involving close to-field constraints and lossy background media can be analyzed using convex optimization.
