| 摘 要： | 从理论上分析了螺旋天线的设计原理,利用阿基米德螺旋天线实现了一款K波段的高频宽带螺旋天线,使高频天线拥有更轻的质量,更低的剖面及更好的圆极化性。最后通过仿真软件CST设计了一款带宽覆盖18.0~26.5GHz的阿基米德螺旋天线,涵盖了整个K波段。结果表明,该天线在整个频段电压驻波比<2,能很好的满足天线收发要求。

| Abstract: | The design of an spiral antenna was theoretically analyzed, and a high frequency broadband K band spiral antenna was realized by Archimedes spiral antenna with lighter quality, lower profile and better circular polarization Finally, an Archimedes spiral antenna cover the band from 18.0 GHz to 26.5 GHz was designed through simulation software CST , covering the entire K band. The results showed that the voltage standing wave ratio of the antenna was less than 2 in the whole frequency band, which could well meet the requirement of transmit receive of an antenna. |
