Abstract: Methods and systems are described for proximity condition detection of a recovery from sensor proximity saturation caused by water immersion of a user device. The device transmits data at a first transmit power level using an antenna. In one system, a proximity condition checker determines that a first proximity sensor and a second proximity sensor are saturated in an unknown state after a power event where the saturation caused at least in part by the presence of water in proximity to the first proximity sensor and the second proximity sensor. The proximity condition checker determines that 1) both the first proximity sensor and the second proximity sensor are no longer saturated and 2) water is no longer in proximity to the first proximity sensor and the second proximity sensor. In response, the user device can transmit data at an increased second transmit power level using the antenna.

Abstract: An antenna structure with a radio frequency (RF) circuit, an antenna carrier, and conductive material disposed on the antenna carrier and coupled to the RF circuit slot is described. The conductive material can radiate or receive first electromagnetic energy as a loop antenna in a first frequency band in a second order mode. The conductive material can include a first slot between portions of the conductive material and a second slot between other portions of the conductive material. The first slot or the second slot can radiate or receive second electromagnetic energy as a slot antenna at a second frequency band in a first order mode. The second frequency band can be higher than the first frequency band.

Abstract: Antenna structures and methods of operating the same are described. One antenna structure includes a ground plane, a feed point, an antenna element, and a parasitic element. The feed point can be coupled to the antenna element and can receive a signal to cause the antenna structure to radiate electromagnetic energy. The antenna element includes: a first portion that extends in a first direction from the feeding point at the RF feed; a second portion that extends from a distal end of the first portion; a third portion that extends from a side of the second portion; a fourth portion that extends from the third portion; and a fifth portion that extends from the fourth portion. The parasitic element includes: a sixth portion that extends from the fourth portion; and the seventh portion that extends from the sixth portion to the ground plane.
