Antenna current optimization and optimal design

Antenna current optimization is used to determine optimal currents in the antenna design region. The currents provide understanding, physical bounds, and figures of merits for antenna designs. The problem is formulated as a convex optimization problem expressed in the currents on the antenna structure. These convex optimization problems are solved with a computational cost comparable to a Method of Moments (MoM) solution for an antenna in the same geometry. In this presentation, antenna current optimization and stored energy are reviewed. Numerical results for maximization of the gain to Q-factor quotient and minimization of the Q-factor for prescribed radiated fields are presented.
