Ramadan A. ALHALABI 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).

  • Method of manufacturing a MEMS DVC device
    Patent number: 10403442
    Abstract: The present invention generally relates to a MEMS DVC having a shielding electrode structure between the RF electrode and one or more other electrodes that cause a plate to move. The shielding electrode structure may be grounded and, in essence, block or shield the RF electrode from the one or more electrodes that cause the plate to move. By shielding the RF electrode, coupling of the RF electrode to the one or more electrodes that cause the plate to move is reduced and capacitance modulation is reduced or even eliminated.
    Type: Grant
    Filed: June 21, 2017
    Date of Patent: September 3, 2019
    Assignee: CAVENDISH KINETICS, INC.
    Inventors: Robertus Petrus Van Kampen, Ramadan A. Alhalabi
  • Techniques of tuning an antenna by weak coupling of a variable impedance component
    Patent number: 9812780
    Abstract: The present invention generally relates to small antennas suitable for mobile devices operating in the high frequency and radio frequency bands in the range 100 MHz to 5 GHz. The antennas may be coupled to a DVC such as a MEMS DVC. The antenna may be coupled to a printed circuit board disposed inside of the mobile device, such as a mobile phone or smart phone.
