Wideband pulse response of compact filter-antenna under impact of an EMP

Research on time-domain responses of the compact filter-antenna of communication system in the presence of an in intentional electromagnetic pulses (EMP) is carried out in this conference paper. An efficient numerical method based on FDTD method is implanted for studying an EMP coupling with some typical compact filter-antennas widely used in the communication systems. Our developed program code is used to capture the responses of the compact filter-antennas. The time-domain induced voltages characteristics of the antenna illuminated by different incident EMPs are shown and compared in detail. These results are useful for further evaluating electromagnetic environment and electromagnetic protection of some complex communication.
