摘    要:为了解决全球卫星定位系统中圆极化天线的馈电问题,基于威尔金森功分器理论和宽带移相器理论,介绍了1种用于全球卫星定位系统的微带功分器。利用HFSS(高频结构仿真器)对关键的参数进行分析和评估,从仿真结果可以看出,所设计的功分器隔离度高,体积小,驻波比低,且具有移相功能,可以用在GPS(全球卫星定位系统),GALLEO("加利略"定位系统),GLONSS(俄罗斯的"格鲁纳斯"定位系统)和我国自己的COMPASS全球卫星定位系统中作为宽带圆极化天线和天线阵列的馈电网络。

关 键 词:功分器  移相器  全球卫星定位系统  北斗

Abstract:A wideband power divider based on wilkinson power divider and wideband shifter was presented for circularly-polarized antenna fed network used in Globle Positioning System.The key parameters of the power divider was analyzed and estimated by using electromagnetic solver,HFSS (High Frequency Structure Simulator).From the results,the power divider had higher isolation,smaller size,lower VSWR(Voltage Standing Wave Ratio),and had a shifter.Therefore,the proposed power divider can be used in GPS(Global Position System),GALLEO,GLONSS and COMPASS as a fed network used in circularly-polarized antenna and antenna array in Globle Positioning System.
Keywords:power divider  shifter  globle positioning system  COMPASS
