| 摘 要： | 对八木微带天线进行了研究。仿真设计一种宽带宽波束圆极化八木微带天线,在中心频率上实现了波束由侧射向端射偏转26°,频率带宽达800MHz,0dB主波束宽度为110°;采用Wilkinson微带功分器产生两路幅度相等相位相差90°信号对天线进行馈电,实现了圆极化。同时研究了在设计天线中参数对于八木微带天线主波束偏转角度的影响,得出了偏转角度随各参数变化的一般规律。

| Abstract: | The microstrip Yagi antennan is studied.The simulation design of a wide-band wide-beam circular polarization microstrip Yagi antenna is implemented,which realizes 26°beam deflexion from side-fire to end-fire at center frequency,800MHz frequency bandwidth and 110°main beam bandwidth at 0dB.The antenna is fed by two signals which have the same maximum available gain but 90°phase difference produced by Wilkinson microstrip power splitter,and realize the circular polarization.The influence of the parameter variation on the beam deflexion of the microstrip Yagi antenna in the antenna design is analyzed.The normal law of the variation of the deflection angle with the parameters is obtained. |
