| 摘 要： | 通过Ansoft HFSS 9.0和Matlab软件分析有限尺寸金属片对折合偶极子天线性能的影响。采用矩形且与天线长度比约1.25的有限尺寸金属片,水平对称放置于天线一侧。天线采用结构简单、输入阻抗易于调试的折合偶极子天线。仿真结果表明,通过调整折合偶极子天线与金属片之间的距离可以调节天线的辐射方向,实现较高的增益和阻抗周期变化。此结果已在实际应用中得到验证并可为RFID便携式天线等设计提供参考。 |

| Abstract: | This paper associates the application of Ansoft HFSS 9.0 and Matlab to analyze the effect of a metal plate to antenna.The plate which is horizontally and symmetrically placed beside the antenna has rectangular shape and finite size,the size ratio is 1.25 to the antenna.A folded dipole antenna is used as the antenna,which configuration is simple and input impedance can be achieved easily.From the simulate results,the directivity of radiation pattern is tuned up,stronger gain and periodically changed impedance are realized on the dependency of distance between the plate and antenna.And all the results also have been validated in practice.The paper gives a reference to the design of RFID portable antenna and so on. |
| Keywords: | folded dipole finite size metal plate radiation pattern gain impedance |
