摘要
为了实现天线的高增益特性,利用了基于有限元数值计算方法的电磁场仿真软件,设计了一种新颖的高增益平面微带准八木天线。该天线采用单面微带形式,使用了简单的共面波导(CPW)馈电,极大的简化了馈电网络,减小了天线电尺寸。天线通过引入匹配枝节,使其具有了良好的阻抗匹配性能,显著提高了天线的辐射效率。仿真结果证明该天线在保持了较宽带宽的前提下,其增益明显高于同类常规八木天线,达到10.19dBi。
In is presented. The the network feed, order to achieve the high-gain antenna characteristics, a new high-gain planar quasi-Yagi antenna microstrip antenna in the form of single-side, the use of a simple CPW feed has greatly simplified reducing the size of the antenna. Through the introduction of the antenna matching side so that it will have a good impedance matching performance, significantly improved the efficiency of the antenna radiation. Simulation results show that the antenna while maintaining a wide bandwidth on the premise of the gain was significantly higher than similar conventional Yagi antenna to 10.19 dBi.
