Optimization of the 0.4 m Monocone Antenna Using Resistive Loading for Pulse Radiation

In order to improve the low-frequency absorption capacity and reduce the voltage reflection at the end of the monocone antenna, the effect of loading an impedance matching loop on reflected voltage is studied in this paper from aspect of numerical calculation and experimental verification. The results show that adding an impedance matching loop between the end of the cone and the end of the ground plane, on the one hand it can improve the low-frequency absorption capacity of the monocone antenna, on the other hand, it can reduce the reflected voltage at end of the monocone antenna.
