Toshihiro Tsuru 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).

  • Surface-mounted antenna, antenna device using the same, and radio communication equipment
    Patent number: 8384598
    Abstract: A surface-mounted antenna has a base having a substantially rectangular parallelepiped shape, an antenna element formed on the surface of the base and having a first radiation electrode subjected to direct power supply, and an antenna element formed on the surface of the base and having a radiation electrode subjected to capacitive coupling power supply. With this, the smaller surface-mounted antenna of a combo antenna type can be provided.
