biconical horn
1.A broadband millimeter wave omnidirectional asymmetrical biconical horn antenna was investigated. A ridge waveguide coax line transition structure was designed to solve the feed problem of biconical horn antenna in millimeter wave band and to meet the engineering requirement that the input port of antenna must be a waveguide. The measurement data of omni directivity and input VSWR in the 26 40GHz band show good agreement with the design.
