一种可用于北斗卫星信号接收的微带天线设计

摘要

基于微带天线技术提出一种应用于北斗导航系统的新型天线设计。该天线采用FR⁃4衬底上的弯曲微带和含有通孔的微带贴片实现。天线的小型化设计可使其更好地应用于北斗导航之中。与此同时，与常规的天线相比，该天线拥有更好的反射系数。实验结果表明，这里设计的天线非常适用于北斗导航系统，进而可应用于车辆导航系统之中。%A novel antenna design method for compass/BeiDou navigation satellite system (CNSS) has been proposed in this paper. The antennas are implemented by meandering micro⁃strips and the micro⁃strip patch with via⁃hole on FR⁃4 sub⁃strates. The miniaturization design of the antenna can make the antenna used for BeiDou navigation much better. In addition, the microstrip antenna can achieve better reflected coefficient than conventional antennas. The experimental results showed that the proposed antenna is suitable for CNSS and also can be applied to the vehicle navigation system.
