适于共用孔径的可重构天线技术

Reconfigurable Antennas Technology Being Applicative for Shared Aperture

现代通讯电子设备随着射频系统数量和功能需求的增加,其承载空间不足的问题将日益突出。由此,开展系统综合射频技术(包括天线的共用孔径技术)的研究和应用,使得多个或多种功能的天线最大限度地共享同一个设备孔径,具有重要的意义。可重构天线具有常规天线不可比拟的优越性,它通过多样的可重构设计手段,可以为解决高性能与小孔径的矛盾问题提供较丰富的技术途径。结合现阶段一些国内外可重构天线的具体设计实例和最新技术动态,重点围绕有效实现电子对抗系统综合射频中的天线共用孔径的现实问题和需求,分析并肯定了可重构天线技术对解决该问题和满足相关需求的适用性,并就其未来的技术发展趋势进行了综述。

Given the growing need of RF modules both in quantity and functions,the volume and weight of modern electronic communication devices would become larger and even out of control. Thus,it is significant to develop integrated RF technology to share one aperture among multiple antennas to the maximal extent. Reconfigurable antennas,that have more various designing skills than traditional antennas,provide an opportunity to solve the problem. This paper analyzed some recent design examples on reconfigurable antennas. Then it demonstrated that reconfigurable antennas technology is applicative for shared aperture in the integrated RF system,especially can meet the integrated needs of electronic warfare system. Moreover,this technology's developing tendency is summarized.
