We report here on an optimal configuration of antennas using multi mono-pole systems. In order to optimize the position and length of antenna, the transmission efficiency are analyzed by finite difference time domain (FDTD) method, which is known for its usefulness and simplicity to calculate to electromagnetic field. The relation between the antenna length and transmission efficiency was investigated. First this report shows that experimental data up to now. Then the microwave transmission is calculated by using poynting vector. When transmission value of microwave is calculated, we varied the parameters such as antenna length, yoke length and number of antennas respectively. Finally, we obtain on guiding design principle of ion engines by comparing experimental data and numerical calculation conclusions.
