In an example, a computing device may include a first radio device including a first antenna, a second radio device including a second antenna, and a basic input/output system (BIOS). The BIOS may establish a communication with the first and second radio devices. Further, the BIOS may receive first transmission status information associated with the first antenna from the first radio device and second transmission status information associated with the second antenna from the second radio device. Furthermore, the BIOS may detect a condition indicative of a combined transmit power of the first and second antennas exceeding a radio frequency exposure threshold based on the first and second transmission status information. The BIOS may instruct the first radio device, the second radio device, or both to perform a mitigation action to maintain the combined transmit power at or below the radio frequency exposure threshold.

Specific absorption rate mitigations

An example mobile computing device includes: an antenna capable of switching between a plurality of antenna patterns; an image sensor to capture image data representing an environment of the mobile computing device; a depth sensor to capture depth data representing the environment of the mobile computing device; a processor connected to the antenna, the image sensor and the depth sensor, the processor to: obtain the image data and the depth data; select a designated antenna pattern from the plurality of antenna patterns based on the image data and the depth data; and control the antenna to use the designated antenna pattern.

Selection of antenna patterns based on image data and depth data

The present disclosure relates to a compact antenna system within a dielectric housing of an electronic device, capable of achieving improved reflection performance. The antenna system includes a ground plane and an antenna PCB. An antenna microstrip feed on a side of the antenna PCB comprises a first part of a radiating antenna element. The antenna PCB is connected to the ground plane by a central conductor of a coaxial cable which forms a ground path. An outer conductor of the coaxial cable carries RF signals to the antenna PCB, allowing the RF signals to freely radiate along a length of the coaxial cable and acting as a second part of the radiating antenna element. The coaxial cable does not interfere with, and can even enhance a radiation pattern of the antenna microstrip feed.

Antenna radiators formed by coaxial cables

An example apparatus may include a first antenna having a first radiator and a first ground plane and a second antenna having a second radiator and a second ground plane. In some examples, a hybrid antenna may be formed through coupling of the hybrid antenna to components of the first antenna and the second antenna. The hybrid antenna may include a third radiator. In some examples, an electrical interface may be disposed between the first antenna and the second antenna. In this regard, the electrical interface may couple the first ground plane to the second ground plane to form the third radiator.

Hybrid antennas

An example radio frequency (RF) front-end module is described, which may include a printed circuit board (PCB) including a ground plane, an RF integrated circuit (RFIC) including RF components mounted on the PCB, and an antenna array on the PCB. The antenna array may operate at a first resonant frequency in a wireless communication network. Further, the RF front-end module may include a slot defined in the ground plane to provide a second resonant frequency in the wireless communication network. The second resonant frequency is lower than the first resonant frequency.

Front-end modules with ground plane slots

In an example, an electronic device may include a housing and a display panel disposed in the housing. Further, the electronic device may include an input assembly disposed in the housing abutting a side of the display panel. The input assembly may include a printed circuit board (PCB), a sensor disposed on the PCB, and a first keep-out zone defined on the PCB on a side of the sensor. Further, the electronic device may include an antenna disposed in the first keep-out zone of the PCB.

Printed circuit board antennas

An example device includes a conductive housing. The conductive housing has a slot containing a dielectric material. An antenna includes a resonating element disposed within the slot. A first connector is disposed within the slot. A second connector is disposed within the slot. The resonating element of the antenna is located between the first connector and the second connector.

Antennas and connectors located in slots

An example radio frequency (RF) front-end module may include a printed circuit board (PCB) including a ground plane, an RF integrated circuit (RFIC) including RF components mounted on the PCB, and an antenna array on the PCB. The antenna array may operate at a first resonant frequency in a wireless communication network. Further, the RF front-end module may include a slot defined in the ground plane to provide a second resonant frequency in the wireless communication network. The second resonant frequency is lower than the first resonant frequency.
