Abstract：A novel resistively loaded monocone with wide bandwidth and low reflectivity was proposed in this paper. To solve the time window caused by limited length, eight non-inductance resistors networks were applied for the distributed impedance end-loading. Reflections occurred from either the end of cone or the edge of the ground plane was reduced significantly and the operational frequency band-width was widen effectively after loading, especially for the low frequency. The result shows that the measured maximum S11 is less than -17dB from DC to 1GHz for the resistively loaded monocone with length of 1.5m, which broken the time window constraints caused by limited cone length and greatly extended the application for pulse E-field calibration. Correspondingly, the calibration range of measuring system is pushed from ultra-short pulse limited by time window to NEMP with more than 20ns pulse width, as well as for the gain and bandwidth measurement of regular antenna.
