“…The topology of the principal element in the RF pulse generator, namely the coaxial NLTL, determined the choice of both the design and characteristics of the antennas which were (a) a conical antenna with a disc-shaped ground plane (disc-cone dipole, DCD), and (b) a half-circular reflector impulse antenna ('Half-IRA' type, [8]) in which the parabolic reflector is driven by a symmetrical dual strip-line horn. When selecting these as QHWB emitters, the following advantages of coaxial systems are taken into account,…”

Experimental results and data of numerical simulations are presented, concerning generation of wideband radio frequency (RF) oscillations in a nonlinear transmission line (NLTL) which contains a pre-magnetized core of ferrite material. Emphasis is made on the means for extracting the RF signal from the line, in order to radiate it into free space. Antennas of two types that can be used for the purpose are considered, both featuring a coaxial design. This permits availing of the principal advantages of coaxial systems, such as operation in the mode of a traveling TEM wave; wide range of the transmitted frequencies, and a reasonably simple design. The antennas studied, specifically a disc-cone dipole (DCD) and an impulse reflector antenna ('Half-IRA', or HIRA type) differ significantly in effective width of the radiated spectrum and in spatial characteristics of the radiated field in far region.
