An irnpulse antenna is one of the key instruments for a pulse radar and transient electromagnetic field measurements. A design of the wideband impulse antenna for transient field measurements is described and some measured results are presented in this paper. The results show thatthis antenna has the characteristics of both the high waveform fidelity and the wideband. It can radiate or receive nanosecond pulse signals efficiently. The fabricated antennas have been applied in atransient electromagnetic measurement system.
