摘要
为了满足GPS定位准确性和可靠性的需要,要求天线在GPS两个频率上实现圆极化.该文介绍一种通过单个探针馈电的双层正方形切角的微带贴片天线.此天线采用不同介电常数的微波陶瓷基片,与常规的双频圆极化天线相比,其尺寸减小了且没有在两层贴片间引入空气层,结构紧凑,便于加工.文中给出了天线的详细设计及实验结果,并进行了讨论.实测结果证明了该设计的有效性.
In order to meet the required precision and reliability for the globe positioning system (GPS), a dual-band circularly polarized (CP) antenna is needed. This paper describes a new design of a probe-fed stacked CP microstrip antenna with two corner-truncated square patches overlapped without air-gap. Compared with the conventional dual-band CP antenna with an air-gap layer between two patches, the size of this antenna is reduced and its fabrication is easier. Details of the proposed antenna design and experimental results are presented and discussed. The measured results show validity of the design.
