Summary: 
In this paper, we study a low profile top loaded monopole antenna. By changing the number, thickness, position and shape of post(s), the input and radiation characteristic due to parameters of matching post(s) are investigated. The low profile top loaded monopole antenna (TLMA) is known as a suitable way for antenna's miniaturization. But it is also reported that the parameters of matching post influence the input and radiation characteristic greatly. The FDTD method is well suit for use in analyzing both the plate and wire structure. And to improve the calculation effect efficiency, the non-uniform mesh FDTD algorithm is used. From the measurement and simulation results, we propose the most suitable parameters of matching structure for low profile top loaded monopole antenna.
