N2 - This paper explores the potential of antenna's bandwidth enhancement and gain control by taking advantage of the third dimension available through three-dimensional (3D)-printing technology. As a proof-of-concept, an ultra-wideband bowtie antenna is proposed using a novel design methodology which involves defining 3D piecewise-linear rate arms and an advanced optimization algorithm based on Trust Region Framework (TRF). Polylactic acid (PLA) thermoplastic is used to simulate the dielectric part of the antenna. The antenna can be fully manufactured using 3-D printing technology. The proposed antenna demonstrates 110% increase in bandwidth in comparison with the initial planar structure. Additionally, it is demonstrated that the gain of the antenna can be controlled by tuning the length and height of the 3D piecewise-linear rate arms in the structure of antenna.
