Abstract
In this paper, a wideband LC oscillator which is composed of a high voltage switch and a fat dipole antenna was designed and radiation characteristics are analyzed. A Marx generator was used as a high voltage pulse generator of the proposed wideband LC oscillator and $90^{\circ}$ corner reflector was used to obtain high directivity. According to simulated and measured results, 3 dB bandwidth of high voltage switch without fat dipole based on the received power is about 9%(${\lambda}_1=0.7\;m$) and bandwidth Is about 30%(${\lambda}_2=1\;m$) by using the LC oscillator containing high voltage switch and fat dipole. Consequently, fat dipole affects not only radiating power but also operating frequency and bandwidth of the LC oscillator. This study will be useful to determine operating frequency and radiating power when we design LC oscillator which uses a high voltage switch and a fat dipole.
