3D-printing has been used for rapidly prototyping a low-cost and light-weight dielectric zone plate Fresnel lens (FL). This lens was comprised of four dielectric zones and they were fabricated in one process with the tailored permittivities. Measurements show that this lens provides 7.3 to 12.8 dB gain enhancement over the frequency band from 8 to 12 GHz.
This paper presents the design and fabrication of a zone plate Fresnel lens. 3D Printing is used for rapid prototyping this low-cost and light-weight lens to operate at 10 GHz. This lens is comprised of four different 3D printed dielectric zones to form phase compensation in a Fresnel lens. The dielectric zones are fabricated with different infill percentage to create tailored dielectric constants...
