Richard D. English has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Device for coupling radio frequency energy from various transmission lines using variable impedance transmission lines
    Patent number: 6771143
    Abstract: An apparatus and method for coupling energy from a transmission line is provided. The apparatus includes a contact designed to “tap” into an inner conductor of the transmission line 100 through an aperture in an outer conductor of the transmission line. A portion of the contact may be coiled (e.g., a spring) and the coil's characteristics may be varied to control the insertion loss and coupling loss of the apparatus. For example, the wire size, coil diameter, number of turns, and pitch design of the coil may be controlled. The apparatus may also include a secondary transmission line connected to the coil and the secondary transmission line may allow additional control over the coupled energy.
