Abstract
Elliptical mirrors can be used to focus electromagnetic waves without losses that occur during propagation through dielectric lenses. As common milled mirrors have a high weight and require time-consuming productions steps, a 3D printed elliptical mirror, coated with a copper spray, is analyzed in this paper regarding its suitability for microwave applications. It can be shown that both mirrors can reach focus diameters below 1 cm, which is suitable for applications like material charakterization. Additionally, this paper presents radar measurement results at 145 GHz that compares the 3D printed mirror with a common milled one. © 2018 IEICE
