等离子体天线研究与发展概况

Research and Development of Plasma Antennas

等离子体天线利用等离子体独特的物理特性,可实现天线的隐身设计,不需改变天线的物理结构,就可对天线的频率、带宽和方向性等参数进行动态重构,它在解决天线隐身和互耦方面有难以估量的发展潜力,是当今天线技术的一大进步。世界上不少大公司都在研究和开发等离子体天线。概述了等离子体天线的特点和类型,介绍了美国、澳大利亚、法国和俄罗斯等离子体天线技术的研究与发展概况。

Using its special physical properties, the plasma antenna can realize its concealing design and reconfignre dynamically the parameters, such as frequency, bandwidth and pattern of the antenna without changing its physical structure. The plasma can make significant contributions to the solving of the problem of concealing and coupling of antenna and this is a big progress in antenna technological field. There are many companies in the world devoting themselves to research and development of the plasma antenna. The paper describes the characteristics and types of the plasma antenna and introduces research and development of the plasma antenna in America, Australia, France and Russia.
