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

Example electronic devices are disclosed herein. In an example, the electronic device includes a housing including a plurality of portions that are pivotably coupled together. The plurality of portions including a first portion including a display panel, a second portion including a user input device, and a third portion including a touch sensitive surface. The second portion is pivotably coupled between the first portion and the third portion. The third portion is pivotable relative to the second portion to cover the user input device with the touch sensitive surface.

Electronic devices with touch sensitive surfaces and user input devices

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

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.
