  • Patent number: 10224604
    Abstract: An antenna device includes two conductor surfaces at opposing positions with a space interposed between the conductor surfaces, a first connection conductor connecting the two conductor surfaces galvanically at one location, and an antenna coil arranged in proximity to the first connection conductor. The antenna coil is arranged at a position at which the antenna coil causes an induced current to flow through the first connection conductor by electromagnetic induction. Currents in the opposite directions flow through peripheral edge portions of the two conductor surfaces, so that a magnetic field is radiated from A space across which the two conductor surfaces oppose each other. This enables a conductor surface defined by a metal plate or the like to be used as a radiation element without providing a slit or an opening in the metal plate so as to avoid problems of a decrease in mechanical strength, design restrictions, and a decrease in an electric field shielding effect.

  • Patent number: 9413055
    Abstract: A base carries a first chip and a second chip oriented differently with respect to the base and packaged in a package. Each chip integrates an antenna and a magnetic via. A magnetic coupling path connects the chips, forming a magnetic circuit that enables transfer of signals and power between the chips even if the magnetic path is interrupted, and is formed by a first stretch coupled between the first magnetic-coupling element of the first chip and the first magnetic-coupling element of the second chip, and a second stretch coupled between the second magnetic-coupling element of the first chip and the second magnetic-coupling element of the second chip. The first stretch has a parallel portion extending parallel to the faces of the base. The first and second stretches have respective transverse portions extending on the main surfaces of the second chip, transverse to the parallel portion.

  • Patent number: 9343810
    Abstract: A very low profile wideband antenna adapted to operate from 30 MHz to 300 MHz or in another desired range. The maximum diameter and height of one embodiment of this antenna is only 60.96 cm and 5.08 cm, respectively. This design is comprised of a fat grounded metallic plate placed 5.08 cm over a ground plane. In one embodiment, ferrite loading strategically placed between the plate and ground plane improves the low frequency gain and the pattern at high frequencies. A minimal amount of ferrite may be used to keep weight low.

  • Patent number: 9099767
    Abstract: The invention relates to an antenna core, an antenna comprising an antenna core, and to methods for producing an antenna core and an antenna. The antenna core used in each case consists of a continuous soft-magnetic strip having a plurality of layers which are stacked one on top of the other and each of which is formed by a section of the strip. The layers are connected to one another by curved sections of the strip at end regions of the antenna core.

  • Patent number: 9041609
    Abstract: An antenna has a radiator formed entirely of thin film and adapted to receive and transmit radio-frequency signals, a connector also formed of thin film and adapted for connection to a transmitter, and a fuse formed of the same thin film as the radiator and connector and connected therebetween. The fuse is of a narrower width than the antenna and connector parts and so dimensioned as to melt if a radio-frequency signal greater than a predetermined magnitude is transmitted through it from the connector part to the radiator part.

  • Patent number: 9035843
    Abstract: The ferrite-loaded, Fabry-Perot Cavity antenna uses a novel superstrate based beam scanning/shaping mechanism by optimally placing three magnetized ferrite cylinders within the cavity. Beam scan in a certain direction required oppositely located ferrite cylinder to be axially biased using externally controlled DC magnetizing field. The FPC utilizes a composite dielectric superstrate to inversely relate the mainlobe-to-sidelobe ratio with scan-angle, which demonstrates larger reduction in side lobe level with increases angle of beam scan. The designed 10 GHz ferrite-loaded FPC antenna has dimensions of 6.4 cm×2 cm×1.6 cm. It achieves a ?10 dB impedance bandwidth of 525 MHz, directivity of 11.04 dB and a broadside beam steering range of ±12° for 200 kA/m (0.25 T) changes in the externally applied axial magnetizing field.
