AHMED SHEHATA ABDELLATIF 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).

  • Tunable phase shifter wherein phase shift is changed by varying a distance between an image guide and a dielectric perturber
    Patent number: 11374294
    Abstract: A tunable phase shifter is provided which includes a dielectric substrate, a transmission line formed based on the dielectric substrate for carrying input and output signals and a dielectric disturber placed on top of the transmission line. The phase shifter further includes a phase shifting mechanism for adjusting at least one of a distance between the transmission line and the substrate and a distance between the transmission line and the dielectric disturber to effect phase shift.
    Type: Grant
    Filed: October 30, 2020
    Date of Patent: June 28, 2022
    Assignee: C-COM SATELLITE SYSTEMS INC.
