摘要

提出了一种渐变折射率透镜天线的设计方法。该方法包括在满足设计边界条件的空间区域中提出相位函数和重新缩放光路。后者允许我们调整透镜的折射率。设计的透镜长度为6λ，光圈宽度为8.7λ。最高要求的折射率是1.6。获得了25.4 dB的指向性值和-24 dB的旁瓣电平。使用COMSOL验证设计功能。

A Closed-form Design Method for GRIN Lens Design

A design method for graded-index lens antennas is proposed. The method consists of proposing a phase function in a region of space that meets the boundary conditions of the design and rescaling the optical path. The latter allows us to adjust the lens’s refractive index. The designed lens has a length of 6λ, an aperture width of 8.7λ. The highest required refractive index is 1.6. A directivity value of 25.4 dB, and a -24 dB side-lobe level are attained. The design functionality is verified using COMSOL.
