| 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 |
