摘要
通过计算机仿真对微带贴片天线的阻抗和辐射性能进行了仔细研究 ,找出了一些微带贴片几何尺寸与天线特性参数之间的关系 ,在此基础上提出了一种可用于 VSAT站基本上满足 C波段卫星通信对频率、带宽、极化、隔离等要求的微带天线阵元的结构 ,同时利用 FDTD法对其进行验证 ,两结果基本一致。
Gives a detail analysis on the impedance and radiating characteristics of a micro-strip patch antenna by computer simulation. Some relationships between its size and characteristic parameters have been found. A new structure of microstrip antenna is presented based on the analysis, which can be used in VAST station and satisfied with the following requirement of C-band satellite communication: dual-frequency,wide-band, dual-polarization and isolation.Meanwhile,FDTDmethod is used to test the antenna′s charateristic pa-rameters.The result gives a good accordance with the conclusion presented in the simulation
