摘要
由于各种微波射频系统对天线性能的要求越来越高,单个天线不易实现,而阵列天线通过对阵元数量、结构形态、排列方式、馈电幅度和相位的选择与优化,可得到单个天线元无法实现的辐射特性。以对微带天线的矩形贴片的分析为基础,完成Ku波段的4元线极化微带阵列天线设计。利用HFSS仿真软件构建阵列天线的物理模型,利用HFSS宏定义优化天线的尺寸参数,通过数据后处理得出驻波特性、3D增益、增益方向图和电场方向图等曲线。仿真结果表明,该4元微带阵列天线具有低副瓣、高增益特性,可满足天线工程需要。
As various microwave radio frequency systems require higher and higher antenna performance,a single antenna is not easy to realize,while array antennas can obtain radiation characteristics that cannot be realized by a single antenna element by selecting and optimizing the number of antenna elements,structural form,arrangement mode,feeding amplitude and phase.Based on the analysis of rectangular patch of microstrip antenna,the design of Ku band 4-element linearly polarized microstrip array antenna is completed.The physical model of the array antenna is built by using HFSS simulation software,the dimension parameters of the antenna are optimized by using HFSS macro definition,and curves such as standing wave characteristics,3D gain,gain pattern and electric field pattern are obtained through data post-processing.The simulation results show that the 4-element microstrip array antenna has the characteristics of low sidelobe and high gain,which can meet the needs of antenna engineering.
