摘要

介绍了一种结合无线电导航和微卫星遥测应用的新型多波段锥体天线。这种灵活的天线提供独立和易于调节的工作频率设计。此外，该锥体天线在不同工作频率下的辐射方向图相对相似。这种辐射结构的一个关键因素是它的截止波导放置在天线地平面下方，以改善输入端口阻抗匹配，同时最小化天线后方辐射水平。本文进一步介绍了上述天线，并给出了其最新改进。

Multiband pyramidal antenna for radio navigation and telemetry systems

A novel multi-band pyramidal antenna combining radio navigation and MicroSAT telemetry applications was recently introduced by the authors. This flexible antenna provides independent and easily adjustable operating frequency design. Furthermore, the radiation patterns of this pyramidal antenna are relatively similar at the different operating frequencies. One key element of this radiating structure is its cutoff waveguide placed underneath the antenna ground plane in order to improve input ports impedance matching while minimizing the antenna rear radiation level. This paper further describes the above-mentioned antenna and gives its latest improvements.
