提出了一种基于丙烯腈-丁二烯-苯乙烯共聚物（ABS）的高增益三维（3D）印刷W波段反射面菲涅尔透镜天线，以实现毫米波雷达系统的低成本和高增益天线。首先，在传统厚反射面透镜天线的基础上，设计了中心频率为76.5 GHz、直径为250 mm的薄反射面菲涅尔透镜天线。然后，假设制造使用高介电损耗材料，如ABS塑料，两种类型的天线的天线特性的差异进行了讨论，使用有限差分时域（FDTD）分析。最后，使用具有低成本ABS薄膜的商用3D打印机制造反射器菲涅耳透镜天线。测得的增益和方位半功率波束宽度分别为36.0 dBi和1.1°。这些结果与37.2 dBi的FDTD分析结果吻合得很好。
: A high-gain three-dimensional (3D) printed W-band re fl ector Fresnel lens antenna based on acrylonitrile butadiene styrene (ABS) is proposed for practical solution to achieve a low-cost and a high-gain antenna for a millimeter-wave radar system. Firstly, a 250-mm-diameter thin re fl ector Fresnel lens antenna are designed at center frequency of 76.5 GHz, based on a thick conventional re fl ector lens antenna. Then, assuming fabrication using high dielectric-loss materials, such as ABS plastics, the antenna characteristics di ff erence of the two types of antennas are discussed using fi nite-di ff erence time-domain (FDTD) analysis. Finally, a re fl ector Fresnel lens antenna is fabricated using commercially available 3D printer with a low-cost ABS fi lament. The measured gain and the azimuth half-power beamwidth are 36.0 dBi and 1.1°, respectively. These results agree well with the FDTD analysis result of 37.2 dBi.
