  • Waveguide and antenna apparatus for extending connection coverage
    Patent number: 10305175
    Abstract: A wearable wireless communication device comprises a transceiver positioned on a first side of the device, the transceiver comprising a first antenna configured to receive radio frequency (RF) signals transmitted toward the first side of the device. The device is wearable about an object that attenuates reception, by the first antenna, of RF signals transmitted toward a second side of the device. The device further comprises a waveguide electromagnetically coupled to the transceiver, the waveguide terminating in at least a second antenna positioned on the second side of the device. The second antenna is configured to receive the RF signals transmitted toward the second side of the device. The waveguide is shaped to direct received RF signals around the object to the transceiver. The object may in some embodiments be a piece of human anatomy.
