Design of Unintuitive Antenna Geometries Using Additive Manufacturing Techniques

Abstract

Using 3D printing, it is possible to create antenna geometries which are not practically feasible through traditional subtractive manufacturing techniques. There are numerous possible ways to design these geometries, such as body of revolution or extrusion methods. With the aid of multiobjective optimization, these structures can be designed for various goals. Examples include wide bandwidth, high gain, strong circular polarization, and compact size. Additionally, 3D printed antennas can offer reduced cost and weight without compromising these performance goals.
