摘要

用于反射器天线高效照明的过模波纹波导馈电，由于模式相速度的色散，其固有的工作带宽受到限制。实验结果表明，输入模式换能器的频率相关模式产生特性可以补偿色散，并且可以实现极大的工作带宽。

Large Bandwidth Realisation in Dual Mode Corrugated Guide Feeds

Overmoded corrugated guide feedst used for high efficiency illumination of reflector antennas, suffer from an inherently restricted bandwidth of operation because of the dispersion in phase velocities of the modes. Experimental results, obtained with a 2-hybrid-mode feed, show that the dispersion can be compensated for by the frequency dependent mode generation characteristics of the input mode transducer and extremely large bandwidths of operation can be realised.
