摘要

本文提出了一种抛物面反射面天线的多波段馈电设计方案，该方案可以在单个天线中同时工作甚高频和超高频频率范围。对所研制的馈源进行了电动力学建模，优化了馈源特性，使反射面天线效率最大化。制作了一种进料样机，并对其性能进行了测试。提出的馈电设计基于同轴结构，允许通过在现有系统中增加馈电操作范围来扩展反射器天线的功能。随着天线系统的接收和发射部分的技术能力的增长，在反射天线现有馈源的基础上扩大工作频带或增加其他频率范围是一项相当紧迫的任务。此外，考虑天线，基于同轴结构，有几个优点，可以作为一个独立的天线使用，具有良好的带宽和高指向性。

Multi-band Reflector Antenna Feed Design Based on Coaxial Structure

A multi-band feed design for a parabolic reflector antenna, which allows to combine the VHF and UHF frequency ranges operation in a single antenna, is presented in this paper. Electrodynamic modeling of the developed feed was carried out, its characteristics were optimized to maximize reflector antenna efficiency. A feed prototype was manufactured, its characteristics were measured. The proposed feed design based on a coaxial structure allows to expand functionality of reflector antennas by adding the feed operating ranges to existing systems. With the growth of the technical capabilities of the receiving and transmitting parts of antenna's systems - an expansion of working bands or an addion other frequency ranges to the existing feeds of the reflector antennas are quite an urgent task. In addition, a considered antenna, based on a coaxial structure, has several advantages and can be used as a separate antenna with a good bandwidth and high directivity.
