The efficacy of the three-dimensional, rectangular magnetic EZ antenna for use with mesoband high-power microwave (HPM) sources has been demonstrated previously. It overcomes the typical bulky and massive impedance-matching components found currently in most HPM systems, making it an attractive option when space is very limited. However, its extremely compact nature presents practical challenges when dealing with extremely high-power sources due to the associated local field enhancements near the feed and the near-field resonant parasitic element. This letter presents a fully integrated,
high-voltage source and radiating system that has several improvements in the antenna, source, and power system that have not
before been demonstrated. The full system includes a ferroelectric
generator, standing wave oscillator source, and electrically small
antenna ( ) operating at 510 MHz that can be packaged
inside a 15-cm-diameter tube. This small diameter results in a
quarter-wavelength-diameter ground plane, and the effects of this
small ground plane on the radiation characteristics are explored.
The development of a pressurized radome allows for operation at
73.6 kV, significantly higher than previous studies.
