详细介绍了使用印刷电路板技术实现的 2D 宽带 Luneburg 透镜天线的设计。透镜的折射率是通过曲折的交叉微带线和改变其宽度的组合来控制的。直径为 12.4 lambda（圆）的透镜设计用于在 13 GHz 的横向电磁 (TEM) 模式下工作。设计、制造并测量了透镜天线。实测实验天线的半功率波束宽度为4.34度。
The design of a 2D broadband, Luneburg lens antenna implemented using printed circuit board techniques is detailed. The refractive index of the lens is controlled through a combination of meandering crossed microstrip lines and varying their widths. The 12.4 lambda(circle) diameter lens is designed to operate in the transverse electromagnetic (TEM) mode at 13 GHz. The lens antenna was designed, fabricated, and measured. The measured half power beamwidth of the experimental antenna is 4.34 degrees.
