Zusammenfassung:A Fresnel phase lens for a 5G antenna is described herein. The Fresnel phase lens includes a glass-ceramic material having a first major surface and a second major surface. The first major surface and the second major surface define a thickness therebetween, and the first major surface defines a plane. The glass-ceramic material includes a first plurality rings having first ring surfaces in the plane and a second plurality of rings having second ring surfaces at a first depth into the thickness and below the plane. The glass ceramic material is transparent to electromagnetic radiation having a frequency of from 20 GHz to 100 GHz.
