The size of the shortwave antenna is a major obstacle to its application.The impact of top-load on the antenna performance is analyzed.The top-loaded monopole antenna is selected as the object of study and simulation.By changing the values of parameters such as the number,angle,length and diameter of the top-line,we simulate and analyze the impact of various parameter changes on the antenna performance.The results show that the top-load can effectively reduce the resonant frequency of the antenna and can realize the miniaturization of the antenna.

Key words: monopole antenna;top-load;miniaturization of antenna
