准八木(Quasi—Yagi)天线是一种基于传统八木天线的宽带平面微带天线,具有良好的增益特性.
仿真和测试结果均表明:准八木天线有效地实现了超宽带、小型化、高增益,并且在水平方向上天线的能量辐射范围比较大,而在垂直方向上能量辐射相对集中,从而在远距离地面通信中有效增加了辐射能量的利用率,可以实现定向远距离地面宽带通信
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( Ansof t 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4.6.4 GH z,在中心频率5.6 GHz 处,峰值增益约为10.2 dB,前后比约为21dB,与仿真结果基本吻合.
Quasi Yagi antenna ( Quasi - Yagi ) is based on a traditional Yagi antenna broadband planar antenna,has a good gain characteristic.Simulation and test results show that:the Quasi-Yagi antenna effectively realizes the miniaturization,ultra wide band,high gain,and in the horizontal direction antenna radiation energy range is relatively large,and in a vertical direction of energy radiation is relatively concentrated,resulting in long distance communication effectively increases the radiation energy utilizing rate,can achieve directional long distance ground broadband communicationBased on the Yagi antenna structure design and production of a quasi Yagi type broadband microstrip antenna with high gain,using 3D electromagnetic simulation software ( Ansof t HFSS ) simulation design,in the single to implement structural basis,by increasing the director number achieves a high gain and wide bandwidth.Actual test results show:antenna operating band at 4.6.4 GH Z,at a center frequency of5.6 GHz,the peak gain of about 10.2dB,and about21dB,and the simulation results basically coincide with.
