Review, Simulation, and Comparison of Four Foldable Rectangular-Pulse Generators

Based on two lines, a switch, and a load, four types of pulse generators can form, which are the single-line generator, the Blumlein-line generator, the double-width-line (DWL) generator, and the cascade-line generator. All these four types of generators have the planar forms and the coaxial forms. In addition, they can be folded to halve the total length. In this article, these four types of generators are reviewed, simulated, and compared. In addition, two kinds of novel folded coaxial rectangular-pulse generators are proposed.
