A small size resonant antenna for high power applications

One way of designing high power mesoband sources uses a wideband source to drive a self-resonant antenna. A self-breakdown switch is used to discharge the antenna after charging it to the breakdown voltage of the switch. The antenna resonates at its quarter wavelength. In many high applications it is advantageous to: reduce the size of such source for a given resonance frequency, and increase the number of the radiated cycles after each switch closure. In the paper, we propose a new design for a conical helix antenna that help in achieving these two goals. Numerical simulations are used to compare the radiated far-field from our new design to those from conical helix and biconical designs.
