  • Patent number: 11342662
    Abstract: There is described a device for switching communications comprising a circuit board as well as first, second, and third antennas. The first antenna is coupled to the circuit board, and the first antenna is focused on a first direction and based on a first wireless technology. The second antenna is coupled to the circuit board, and the second antenna is focused on a second direction and based on the first wireless technology, in which the second direction is different from the first direction. The third antenna is coupled to the circuit board, and the third antenna is focused on a third direction and based on a second wireless technology, in which the second wireless technology is different from the first wireless technology. The second antenna may operate as a shield for the third antenna.

  • Publication number: 20210273324
    Abstract: There is described a device for managing communications comprising a sensor, first and second antennas, and first and second shields. The sensor has a field of view and includes a first side and a second side, in which the second side is substantially opposite the first side. The first antenna is positioned offset from the first side of the sensor, and the second antenna is positioned offset from the second side of the sensor. The first shield is positioned adjacent to the first side of the sensor and a first distance from the first antenna, and the second shield is positioned adjacent to the second side of the sensor and a second distance from the second antenna. The first shield focuses the first antenna toward the field of view, and the second shield focuses the second antenna toward the field of view.

  • Patent number: 10886596
    Abstract: The present application provides a handheld wireless communication device. The handheld wireless communication device includes a two part housing having an upper housing and a lower housing, the upper housing and the lower housing being rotatably coupled together via a hinge. The upper housing and the lower housing through a relative movement via the hinge can transition between an opened position and a closed position. The lower housing has a first conductor including one or more tuned structures and has a second conductor including one or more tuned structures, where each of the tuned structures of the first conductor and the second conductor are adapted for at least one of transmitting or receiving electromagnetic energy having a respective predefined range of frequencies in support of wireless communications.

  • Patent number: 10031238
    Abstract: Systems and methods for improved Global Positioning System (“GPS”) function employ two multiband, multiport antennas to receive GPS signals. The antennas also serve WiFi frequencies, and the system utilizes the received WiFi signal strength to correct the GPS reception pattern for detuning due to user contact or other factors. The correction is made via selective combination of the GPS signals from the antennas. In addition, a phase shifter in one of the signal paths is used to account for changes in device orientation and to maximize the upper hemisphere component of the GPS reception pattern.
