| 摘要: |
| 采用非均匀网格时域有限差分(NU-FDTD)方法，对单层印刷对数周期阵子天线(PLPDA)进行了电磁仿真，分析了单面和双面介质盖板对PLPDA性能的影响，得到了PLPDA的驻波和方向图特性，并进行了实验验证，分析结果与实验结果吻合得较好。 |

| Abstract: |
| Based on the method of non-uniform grid-FDTD,a monolayer printed PLPDA was analysized.The influence of the single and double coated dielectric cover on the performance of the PLPDA was also discussed.Through electromagnetic simulation to the PLPDA, the standing-wave-ratio and directional-pattern of the antenna were got and the results were validated by experimentation.The analysis and experimental results fit perfectly. |
| Keywords: non-uniform grid finite-difference of time-domain printed log-periodic dipole array antenna |
