Abstract: An example electronic device includes a first housing including, a first display, a first antenna, a second antenna, and a first rotational motion sensor. The electronic device also includes a hinge including a bend sensor. The electronic device further includes a second housing rotatable coupled to the first housing via the hinge. The second housing includes a second display, a third antenna, a fourth antenna, and a second rotational motion sensor. The electronic device further includes a communication device to select two of the first antenna, the second antenna, the third antenna, and the fourth antenna based on the first rotational motion sensor, the second rotational motion sensor, and the bend sensor. The communication device is also to transmit and receive data via each of the two selected antennas.

Abstract: Techniques for controlling RF output of portable devices are described. In an example, an indication of a mode of a portable device is received. The mode is based on an inclination of the portable device. The inclination is measured in reference to a screen of the portable device and a horizontal surface. Based on the mode, an RF power level defined for the mode is determined. The RF power output of the portable device is controlled based on the RF power level.

Abstract: Examples of an integrated slot antenna are described. The integrated slot antenna comprises a first slot, a second slot and a separating member. The first slot is an open-ended slot and is coupled to a first antenna member to form a first slot antenna. The first slot antenna operates in a first predetermined range of frequencies. The second slot is a close-ended slot and is separated from the first slot by the separating member.

Abstract: An antenna assembly includes a ground plane, a radiator, and a resonant circuit. The ground plane has a slot with an open end. The radiator spans the slot and has a shape configured to radiate electromagnetic energy at a first frequency and at a second frequency. The resonant circuit spans the slot in parallel with the radiator and is positioned nearer the open end than an opposite end of the slot.

Abstract: An antenna device for a signal having a frequency within an operation band comprises a ground element, a radiating element short-circuited to the ground element, a positive feed connected to the radiating element, and a ground feed coupled to the ground element by a capacitive element. The capacitive element is a substantially open circuit for signals having a frequency lower than the operation band. The capacitive element is a substantially short circuit for signals having a frequency within or higher than the operation band.
