Latest Patents
One of Okubo's latest patents is for a multi-frequency antenna. This invention features a dielectric carrier that is disposed on a substrate and formed with a recess. A first antenna element is provided on at least one face of the carrier and is electrically connected to the substrate. Additionally, a second antenna element is provided as a ceramic antenna and is disposed in the recess. The design includes a first dielectric layer between the two antenna elements and a second dielectric layer between the substrate and the second antenna element. The recess is strategically positioned to optimize performance.
Another significant patent is for an antenna device designed for mobile telecommunication terminals. This whip antenna is movable between two positions: one where it is extended from the casing of the mobile communication terminal and another where it is accommodated within the casing. The device includes a built-in antenna and a power feeding circuit housed within the casing. It features a first matching circuit with a specific impedance for when the whip antenna is extended and a second matching circuit with a higher impedance for when the whip antenna is retracted. A switch mechanism ensures that the built-in antenna is disconnected from the power feeding circuit when the whip antenna is in use.
