Abstract: 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 methodology is particularly useful for antennas that are constrained by their electrical size such as small antennas. The antenna design optimization problem is formulated as a convex optimization problem expressed in the currents on the antenna structure. This presentation reviews antenna current optimization and numerical results for maximization of the gain to Q-factor quotient and minimization of the Q-factor are presented.
