摘要:天线是发射或接收系统中经设计用于辐射或接收电磁波的部分,用于接收状态时天线
接收来波,并将其引向连接着传输线的公共馈点。表面电流分布是天线的重要参数。通过以 RWG(Rao.Wilton.Glisson)边元为基础的矩量法,使用Matlab软件工具,对给定结构和入射电磁 信号的接收天线进行分析计算,创建RWG边元,求解阻抗矩阵和矩量方程,得到了天线的表面 电流分布,并将表面电流分布可视化。

Compute of receiving antenna surface currents
CUI Yu—chao (School of lnformafi ̄and Communication Engineering,North University of China,Taiyuan 030051,China) Abstract:Antenna is a part which is designed to radiate or receive electromagnetic wave in transmission or
receiving system,in receiving mode antenna receix,es wave and leads it to common feed point which connects to transmission wire.The distribution of surface currents is an important antenna parameter.To the given
structure and incident electromagnetic wave receiving antenna,through RWG—based momentum method with Matlab software,This paper established RWG elements,solved impedance matrix and momentum equations, achieved the compute of the distribution of.antenna surface currents,and made it visible, Key words: antenna analysis; antenna simulation; surface currents;simulation with Matlab

(1 中北大学仪器科学与动态测试教育部重点实验室,太原030051; 2 中北大学电子测试技术国家重点实验室,太原030051) 摘要:为研究微带天线与安装柱形壳体共形弯曲后工作性能变化,以平面微带天线为基础建模仿真了不同 曲半径的柱面微带天线结构,将平面、不同曲半径柱面的微带天线仿真数据进行了详细分析比较。结果表明: 当平面微带天线弯曲成柱面时,中心工作频率和10相带宽均不会受到影响,但XZ和yz截面上的增益会受到 影响。由此得到矩形微带天线在不同曲半径柱面下工作性能的优劣,为曲面微带天线的研究和实用化设计提 供了准确的理论与仿真依据。 关键词:柱面;共形微带天线;HFSS建模仿真 中图分类号:TN823文献标志码:A

CUI Lili 一,WANG Wei ,MA Tiehua ,DING Yonghong ' (1 Key Laboratory of Instrumentation Science Dynamic Measurement(North University of China),Ministry of Education,Taiyuan 03005 1 China;2 National Key Laboratory of Electronic Measurement Technology,North University of China,Taiyuan 030051 China) Abstract:In order to research the working performance changes of the microstrip antenna after bending with the conformal cylindrical structure,based on the planar mierostrip antenna,modeling and simulation of the different curved radius cylindrical microstrip antenna, making a detailed analysis and comparison of the simulation data of the planar and different curved radius cylindrical microstrip antenna. Simulation results indicate when the planar microstrip antenna is curved,the working center ̄equency and 10 dB bandwidth is not affected, but the gain of ax and is section is affeetedh.hereby obtaining the performance of rectangular microstrip antenna under different radius of the cylindrica1.It prevides accurate theoretical and simulation ̄undation for the study and practical design of a curved surface microstrip
