基于八木天线的结构设计并制作了一个准八木型宽带高增益微带天线,利用三维电磁仿真软件(Ansoft HFSS)进行仿真设计,在已有的单一引向器结构的基础上,通过增加引向器数量实现了高增益和较宽的带宽。实际测试表明:天线工作频段在4.8~6.4GHz,在中心频率5.6GHZ处,峰值增益约为10.2dB,前后比约为21dB,与仿真结果基本吻合。另外,还给出了准八木型高增益微带天线的设计过程,并对具体结构和参数的选择对天线性能的影响进行了比较和讨论。
基于八木天線的結構設計併製作瞭一箇準八木型寬帶高增益微帶天線,利用三維電磁倣真軟件(Ansoft HFSS)進行倣真設計,在已有的單一引嚮器結構的基礎上,通過增加引嚮器數量實現瞭高增益和較寬的帶寬。實際測試錶明:天線工作頻段在4.8~6.4GHz,在中心頻率5.6GHZ處,峰值增益約為10.2dB,前後比約為21dB,與倣真結果基本吻閤。另外,還給齣瞭準八木型高增益微帶天線的設計過程,併對具體結構和參數的選擇對天線性能的影響進行瞭比較和討論。

A microstrip Quasi-yagi antenna based on yagi antenna is designed using software for 3-D electromagnetic field analysis called Ansoft HFSS, and results with high gain and relatively wide bandwidth are presented by adding the directors. The antenna is also fabricated and tested. The working band of the antenna is 4.8 ~6.4 GHz, and the peak gain at the working frequency of 5.6 GHz is about 10.2 dB,the front-to-back ratio is about 21 dB, and it accords with the emulation results. The design process of the microstrip Quasi-yagi antenna is also presented, and the influence of the structure parameters on the performance of the antenna is discussed.
