毫米波天线

本文评述了适用于毫米波和亚毫米波的天线设计。该频段在通信、雷达和遥感方面的应用正在迅速发展,并且需要高性能天线。许多新颖的设计都致力于毫米波特性的开发利用。较短的波长意味着更严格的公差。从而要求更精密、更有效的反射面和馈源喇叭。本文综述了反射面天线、透镜天线、喇叭天线、平面天线、行波天线和集成天线。

Millimetre Wave Antennas

Antennas designed for use at millimetre wave and sub-millimetre wave are re-viewed. The use of these parts of the spectrum for communications, radar and remote sensing isgrowing rapidly and with it the demand for high performance antennas. Many novel designs havebeen developed to exploit the unique characteristics of millimetre waves. The short wavelengthmeans fine tolerances which has led to precision and efficient reflectors and feed horns the paperreviews the current position for reflectors, lenses, horns, planar antennas, travelling wave antennasand integrated antennas.
