This paper describes a novel antenna called the high-power radial line helical array antenna to realize the directional radiation of high-power microwave. This array uses short helical antenna as its radiation element, each helix is excited by the energy coupled by a probe from a radial waveguide. Helices and probes are arranged to form a circular array. This antenna accepts directly an azimuthally...
High-power radial line helical array antenna is a novel antenna developed to realize directional radiation of high-power microwaves. This antenna directly accepts an azimuthally symmetric output of a high-power microwave source and radiates circularly polarized microwave with a boresight peak. It has a high efficiency, a compact structure, and a notable power-handling capacity. Starting from its fundamental...
