Latest Patents
Fred E Ashbaugh's latest patents highlight his inventive prowess. The first patent is for a **High-gain, waveguide-fed antenna having controllable higher order mode**. This invention describes a diverging shell antenna that uses a waveguide to supply the TE.sub.11 mode. A dielectric rod partially contained within the waveguide effectively converts this mode to the dominant HE.sub.11 mode. The design includes features that allow for the controllable conversion of the HE.sub.11 mode into second and third order modes, achieved through predetermined discontinuities in the diverging shell, facilitating optimal control over the antenna's performance.
His second patent, the **Electromagnetic antenna collimator**, proposes a dielectric inset that can be mounted within a conical horn antenna. This innovative device focuses an impinging electromagnetic wave front as a planar wave front at a connected wave guide. Various construction methods aim for size and weight reduction while maintaining the effectiveness of the antenna, utilizing materials with differing dielectric constants, and even incorporating lower density materials like suspended metallic particulates.
