| 摘要: |
| 采用在辐射贴片上增加一个L型寄生贴片的方法,通过仿真优化设计并制作一种带寄生贴片的短路贴片天线,并使用Agilent 8753 ES矢量网络分析仪对天线进行测试,结果表明这种天线可以达到18%的相对带宽(VSWR<2),其方向图与常规短路微带天线类似,可以达到4dB的较高增益。这种短路贴片天线可以有效展宽天线的带宽,具有小型化的特点,且结构简单,易于实现与移动设备的共形。 |

| Abstract: |
| A novel shorted wideband patch antenna with an appended patch inverted by the radiating one is given.The antenna structure is compact and simple,so it is easier to be conformal with moving device.Emulated,experiment VSWR results are given at 2.4GHz,which shows that the design can earn a relative bandwidth(VSWR<2) of 18%.Its pattern is similar to shorted microstrip antenna and the gain is 4 dB.Finally,the influence of the ground size on the antenna characteristics is studied. |
| Key words: antenna appended patch simulation and optimization |
