The application of a shape synthesis process for electrically‐small three‐dimensional (3D) conducting surface antennas is described. A script (shaping manager) links a computational electromagnetics engine and genetic optimisation algorithm, and implements a prescribed process that shapes the antenna from any specified starting shape until a self‐resonant structure is produced whose performance satisfies requirements incorporated into an objective function defined in the shaping manager. Examples of successfully shape synthesized 3D antennas are discussed.
