摘要：
3D-printing has been used for rapidly prototyping a low-cost and light-weight dielectric Fresnel zone plate lens. 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 7.3-12.8 dB gain enhancement over the frequency band from 8 to 12 GHz.
