摘要

本文精确地研究了孔径源馈电的小型扩展半椭圆介质透镜天线(DLA)的光束准直能力。这种分析考虑了透镜的有限尺寸和一次进给的方向性。在内部共振之外，透镜边缘的照明被发现是最重要的，它破坏了致密材料制成的dla的辐射特性。

Role of edge illumination in hemielliptic dielectric lens antenna performance

We study, in accurate manner, the beam collimation ability of a small extended hemielliptic dielectric lens antenna (DLA) fed by an aperture source. This analysis accounts for finite size of the lens and directive nature of the primary feed. Off the internal resonances, which spoil the radiation characteristics of DLAs made of dense materials, the lens edge illumination is found to be of primary importance.
