An electrically-large antenna for transient electromagnetic field measurements

摘要

An electrically large antenna for the measurement of broadband electromagnetic pulses and transients is described. Numerical results obtained from theoretical analyses in both the time and frequency domains are presented. They indicate that the antenna can be used to measure electromagnetic pulses and transients with subnanosecond rise times (bandwidth up to 10 GHz) and has much better frequency- and time-domain receiving characteristics than an equally sensitive Wu-King monopole.
