Radial line helical array antenna is a novel antenna which realizes the directional radiation of circularly polarized high power microwave. This paper put forward a rectangular radial line helical array antenna (subarray), which uses short helical antenna as its radiation element, each helix is excited by the energy coupled by a probe from a radial line waveguide, especially it can be simply assembled...
Mode matching method is a useful way to analyze the mode characteristics during the section change of the waveguide. By applying this method to the radial waveguide and solving specific problems due to the radial transmission of electromagnetic wave, a calculating method in radial waveguide based on mode matching is presented. The scattering characteristic of metallic plates in radial waveguide is...
