Ralf Klukas 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).

  • High performance low cost dipole antenna for wireless applications
    Patent number: 7098860
    Abstract: A printed dipole antenna comprises bent dipole arms connected to respective feed lines formed on opposed surfaces of a substrate. In one particular embodiment, the dipole antenna is provided as a folded dipole, including two or more connector lines to provide an increased frequency range. Two of these dipole antennae may advantageously be combined to an antenna system having a superior radiation characteristic in that the two dipole antennae are arranged to have a different orientation. A corresponding circuitry may then select the antenna, which provides superior operation at a given time.
    Type: Grant

  • High performance low cost monopole antenna for wireless applications
    Patent number: 7064717
    Abstract: A monopole antenna, a monopole antenna system and a data communication device are disclosed in which a high isotropic radiation characteristic is achieved with a minimum substrate area occupied by the antenna. To this end, a substantially T-shaped monopole design is used, wherein end portions of one of the resonating paths are oriented in conformity with respective edges of a substrate.
