摘要
随着卫星导航通信技术的迅速发展,天线作为卫星导航通信系统中的重要部分,在一定程度上决定着卫星导航通信系统的性能。介绍一种用于卫星导航通信系统的双臂螺旋天线,讲述爬行波式螺旋天线的设计过程,并给出最终测试结果。结果表明,该天线具有优良的圆对称半球波束,良好的广角圆极化特性和优良的阻抗匹配特性,其结构简单、紧凑,为通信入站回传提供了一种优良的选择。
With the development of satellite navigation communication, antenna is a very important unit, performance of the satellite navigation communication system is affected by it partly. A new type of bifilar helix for satellite navigation communication system is introduced, and the traving- wave bifilar helix is analyzed briefly. Meanwhile, the design and the test results are given. The results show that the antenna possesses excellent circular hemispherical beam with wide angle circular polarization and better impedance match,and has a compact structure and high integration, it can be applied in CAPS systems successful.
