Continuous Variable Dielectric Constant Luneburg Lens Antenna Based on 3D Printing Technology

Abstract

In this paper, a Luneburg lens antenna with continuously variable dielectric constant is designed and manufactured by using 3D printing technology, which operates at 24 GHz with a maximum gain of 18.1 dBi and the beam scanning is realized by moving the feed. The simulation and measured results show that it has great development potential in the fields of satellite communication and radar tracking.
