Popis: This paper proposes a paraboloidal reflector-based integrated antenna-source (IAS) system for increasing the strength of radiated electric fields in ultrawideband (UWB) pulses. With the transient analysis of a paraboloidal structure, the reflector for an omnidirectional radiation source is designed. The paraboloidal reflector-based IAS system is structurally uncomplicated and compact. The proposed high power wideband radiator has a peak value of 42.9 kV/m at a distance of 40 m and a center frequency of 1.1 GHz. Thus, the strength of electric field rises by 8.9 times compared with that of the system without reflector. It is numerically and experimentally proved that both the far voltage and the UWB gain are significantly increased.
