Patents by Inventor Tsung-Han Cheng

Tsung-Han Cheng 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).

  • Patent number: 9444144
    Abstract: An electronic device is provided. The electronic device includes a conductive housing, a first antenna element, a second antenna element and an insulation structure. The first antenna element is disposed in the conductive housing. The second antenna element is disposed on an external surface of the conductive housing and is opposite to the first antenna element. The conductive housing generates a first current in response to the operation of the second antenna element. The insulation structure penetrates through the conductive housing and extends from at least one side of the conductive housing to the second antenna element. The conductive housing generates an induction current in response to the operation of the first antenna element. The insulation structure blocks the induction current so that the conductive housing generates a second current, and a direction of the first current is the same as a direction of the second current.

  • Publication number: 20150048986
    Abstract: An antenna unit applied to an electronic device is provided. The antenna unit includes an input/output (I/O) element, a conductive wire and a magnetic material. The outer surface of the input/output element has a spiral groove. The conductive wire is disposed in the spiral groove of the input/output element. The magnetic material may be adhered above or/and under the conductive wire according to different designs. Thus, the conductive wire is insulated from the metal of environment or the input/output element.
