  • Patent number: 10171126
    Abstract: Embodiments of front-end module (FEM) circuitry and a communication device are generally described herein. In some embodiments, the FEM circuitry may be configured to provide uplink (UL) multiple-input multiple-output (MIMO) signals and/or UL carrier aggregation (CA) signals for transmission by the communication device. The FEM circuitry may comprise a hybrid coupler to generate a first antenna transmit signal and a second antenna transmit signal. The FEM circuitry may further comprise one or more tunable phase shifters. In some embodiments, the phase shifters may phase-shift a first radio frequency (RF) signal and a second RF signal according to a 90 degree phase difference to generate the hybrid coupler input signals. Accordingly, the antenna transmit signals may be transmitted according to the UL-MIMO configuration.

    Abstract: An antenna device includes a power supply coil coupled to a first power supply circuit operating in a first frequency band, a first conductive member including a first main surface, a second conductive member including a second main surface, a third conductive member, and first connections. The second main surface of the second conductive member is disposed with at least a portion thereof opposing the first main surface. The third conductive member has an area that is smaller than an area of the first conductive member when viewed in a direction perpendicular or substantially perpendicular to the first main surface. The first conductive member, the third conductive member, and the first connections define a loop of a magnetic field antenna in the first frequency band. The power supply coil is closer to the third conductive member than to the first conductive member when viewed in the Z-direction.

  • Patent number: 10084238
    Abstract: Multi-radio antenna apparatuses and stations for wireless networks including multiple radios coupled to a single transmit/receive antenna, in which the antenna is highly synchronized by an external (e.g., GPS) signal. These multi-radio antenna systems may provide highly resilient links. Synchronization may allow these apparatuses to organically scale the transmission throughput while preventing data loss. The single transmit/receive antenna may have a single dish or a compound (e.g., a single pair of separate transmitting and receiving dishes) and connections for two or more radios.

  • Patent number: 10020585
    Abstract: Embodiments of a wide band multi-polarization antenna system are described, which can be attached to the back or front of a soldier's vest or backpack. The antenna system can allow for release of pre-shaped integral radiating elements that spring into a geometric configuration suitable for circular polarization radiation or linear polarization over a desired band of frequencies. The antenna system can provide, when collapsed, linear polarized line-of sight capability over a wide band of frequencies. In a collapsed low-profile state, the antenna system can remain on the soldier, but out of the way for maneuvering.

  • Patent number: 9791490
    Abstract: An electronic device may be provided with wireless circuitry. Control circuitry may be used to adjust transmit power levels for wireless signals, may be used to tune antennas, and may be used to adjust other settings for the wireless circuitry. The electronic device may have a coupler interposed between an antenna and wireless transceiver circuitry. The coupler and a receiver within the transceiver circuitry may be used to make measurements on tapped antenna signals such as transmitted signals and signals reflected from the antenna. By analyzing the tapped antenna signals, S-parameter phase and magnitude information may be gathered that provides insight into whether the electronic device is operating properly and whether an external object is adjacent to the antenna. If an external object is present, the electronic device may limit wireless transmit power and may adjust tunable components in the antenna to compensate for detuning from the external object.
