  • Radome—reflector assembly mechanism
    Patent number: 9577323
    Abstract: In one embodiment, a radome-reflector assembly for, e.g., a microwave antenna, has (i) two semi-circular rims that receive the peripheries of the radome and the reflector and (ii) fixed and adjustable clamps that secure the ends of the rims together. The rims are designed with slanted inner surfaces that engage the periphery of the reflector, such that, when the adjustable clamp is tightened circumferentially, the periphery of the reflector is forced laterally to abut other rim structure to form a metal-to-metal RF seal between the reflector and the rims. Certain assemblies with low profiles and low circumferential forces can be assembled without special tooling using plastic clamps and still achieve good RF seals.

  • Multiband monopole antenna apparatus with ground plane aperture
    Patent number: 9570799
    Abstract: A monopole antenna coupled to a metallic ground plane includes apertures used to steer a radio frequency (RF) beam of the monopole. The apertures may have a length, width, and distance from the monopole based on the wavelength of the RF signal used to drive the monopole antenna. The aperture may be coupled to one or more selective devices, such as PIN diodes, which may short portions of a metallic ground plane near the aperture. The shorted portions of the metallic ground plane provide for steering of the monopole radiation pattern. A circuit board metallic ground plane may include multiple apertures to direct different RF signal frequencies from a single monopole antenna. Multiple monopole antennas may be implemented over a metallic ground plane within a wireless device, each monopole antenna with corresponding apertures.

  • Antenna device and method of setting resonant frequency of antenna device
    Patent number: 9564678
    Abstract: In antenna device, a coil conductor of an antenna coil module and a conductor layer at least partially overlap. A current flows in the conductor layer to block a magnetic field generated by a current flowing in the coil conductor. A current flows along the periphery of a slit and around the periphery of the conductor layer due to a cut-edge effect. Since magnetic flux does not pass through the conductor layer, magnetic flux attempts to bypass the conductor layer along a path in which the conductor opening of the conductor layer is on the inside and the outer edge of the conductor layer is on the outside. As a result, the magnetic flux generates large loops that link the inside and the outside of a coil conductor of an antenna on a reader/writer side to couple an antenna device and the antenna on the reader/writer side.
