摘　　要：微波陶瓷介质加载的四臂螺旋天线,体积显著减小,而性能基本不变,是应用在小型化卫星导航定位设备中的理想天线。在介绍四臂螺旋天线结构组成、工作原理和发展过程的基础上,讨论了陶瓷介质加载四臂螺旋天线的特性和制作方法,并指出了存在问题和今后的研究方向。Recently ceramic-loaded quadrifilar helix antenna （DQHA） was developed as a perfect satellite communications antenna. It has four helix arms and small volume and excellent performance. The characteristic and development of dielectric-loaded quadrifilar helix antenna was reviewed. The introduction of DQHA was focused on its structure, operating principle and the developing process. The problems and its solution were also briefly discussed.
