摘要

本文提出了对先前在meta-horn mba中的工作的两项改进。首先，利用元喇叭的指向性优于传统喇叭，可以通过使用更小的喇叭来提高MBA光束的分辨率。其次，通过特殊设计后变喇叭，使其遵循孔径效率随频率下降的曲线，可以实现二次模式光束的一致性。

Meta-horns improve the performance of multi-beam reflector antennas

Two improvements to the previous work in meta-horn MBAs were presented. First, it was shown that meta-horn's improved directivity over conventional horns can be used to increase MBA beam resolution by using smaller horns. Second, it was shown that secondary pattern beam congruency can be achieved by specifically designing the meta-horn to follow a decreasing aperture efficiency versus frequency curve.
