N2 - We propose a topology optimization strategy for the systematic design of a three-dimensional (3D), conductor-based sub-wavelength antenna. The post-processed finite-element (FE) models of the optimized structure are shown to be self-resonant, efficient and exhibit distorted omnidirectional, elliptically polarized far-field radiation patterns. The computed approximate <i>Q</i> value for this antenna is Q<sub>Z</sub>(ω<sub>0</sub>)≈ 7.74 for ω<sub>0</sub>=2π × 350.8 MHz and it is 1.64 times larger than the theoretical lower bound value.
