Response characteristics and protection techniques of monopole on conductive plane exposed to electromagnetic pulse

Based on the widely used monopole on conducting plane,the response characters of antenna exposed to high electromagnetic pulse,high power microwave and ultra wideband electromagnetic pulse were analysed by moment method,and the time domain and frequency domain response waveforms of the three types electromagnetic pulse coupled to the antenna was calculated.The monopole response waveform of the narrowband pulse is much similar to the incident waveform,the peak current is 100 A,60 A and 10.3 A ordinally,boosting the demand for higher power capacity of the actual high power limiters.
