Currently, When Shielding effectiveness(SE) test was conducted in MIL-STD-188-125-1, The experiments are using Loop antenna, Log Periodic(LP) antenna, Biconical antenna about shielding in the frequency range of 10k∼1GHz. But, Their size in the shielding effectiveness test influences chamber construction costs. And these influences play a role in increased production costs. So spiral antenna to clear antenna size problem was proposed. This antenna has small size and function to cover broad frequency compared to other antennas. To evaluate antenna performance, we use commercial software simulation program. And we observe radiation characteristic changing arm width and distance between arm. First, through magnitude analysis of S-parameter, antenna characteristic according to each arm distance is analyzed. Secondly, through Theta/Degree Vs. dB function and 2D/3D model, radiation pattern of antenna is investigated. Third, radiation energy magnitude and characteristic of antenna is investigated in simulation program.
