摘要

本文将非均匀介质填充的圆柱形吕尼堡透镜与介电常数为常数的材料制成的透镜进行了比较。在ANSYS Electronics Desktop-HFSS中进行电磁建模，并建立了全尺寸模型。详细描述了模型创建的主要阶段和设计难点。结果表明，采用80×40 mm2开放式波导馈送的圆柱形Luneburg透镜，其上、下限于金属板，彼此相距40 mm，透镜半径为237 mm，分析频率为3 GHz。在圆柱透镜部分填充的介电层中，所使用的介电常数为2.6，与3d打印使用的普通塑料相对应。

Comparison of luneburg lens antennas made from homogeneous material

In this article a comparison is made of the cylindrical Luneburg lens of inhomogeneous dielectric filling with the lens made from the material with a constant value of the dielectric permittivity with introduced discontinuities. The comparison is carried out based on electromagnetic modeling in ANSYS Electronics Desktop-HFSS, with the creation of full-size models. The main stages of creating models and design difficulties are described in detail. Results obtained for the cylindrical Luneburg lens fed by an 80×40 mm2 open-ended waveguide, top and bottom is limited to metal plates separated 40 mm from each other, the radius of the lens is 237 mm, the frequency of analysis is 3 GHz. In partially filled dielectric layers of the cylindrical lens, the dielectric used has a constant value of dielectric permittivity equal to 2.6, which corresponds to the common plastics used for 3D-printing.
