Abstract: An electronic device may be provided with peripheral conductive housing structures, a rear wall, and a vent that includes a conductive cowling. The device may include an antenna having an antenna arm coupled to a positive antenna feed terminal and having a parasitic element. The parasitic element may be formed from a conductive trace that is layered onto the rear wall, that is indirectly fed by the antenna arm, and that overlaps a portion of the conductive cowling. The parasitic element may be shorted to a conductive bracket on the rear wall or may be separated from the bracket by a gap. If desired, the conductive cowling may form some or all of a parasitic element for the antenna. The conductive cowling may be indirectly fed by the conductive trace and/or may include an extension that is indirectly fed by the antenna arm.

Abstract: An electronic device may have first and second rear-facing displays, a front-facing display, a cover at a front side overlapping the front-facing display, and an antenna that radiates through the cover. The cover may have a three-dimensional curvature. The device may have an inner chassis and an outer chassis. The antenna may include a radiating element and a ground trace on a flexible printed circuit. To maximize wireless performance of the antenna, the ground trace may be electrically coupled to as much conductive material in the vicinity of the antenna as possible. For example, the ground trace may be grounded to conductive structures in the front-facing display via a conductive cavity for the antenna, may be grounded directly to the outer chassis using conductive screws, and/or may be grounded directly to the inner chassis using conductive screws.

Abstract: An electronic device may have first and second rear-facing displays, a front-facing display, a cover layer at a front side with a central region overlapping the front-facing display and a peripheral region, and wireless circuitry with a transceiver and antennas. The transceiver may convey audio data with left and right earbuds using a non-Bluetooth low-latency-audio communications protocol. The antenna(s) may be mounted at a bottom side of the device overlapping the peripheral region, at a rear side of the device, or may be mounted to a head strap. The antenna(s) may be tilted to optimize field(s) of view, to match polarization of the earbuds, and/or to allow multiple antennas to exhibit orthogonal polarizations. The antennas may include a single antenna that concurrently conveys packets of audio data to both earbuds or may include first and second antennas that concurrently convey audio data to the left and right earbuds.

The new channel is selected based on RSSI measurements are performed by the network node on one or more of the following: the current channel in the current frequency interval, a different channel in the current frequency interval, or a different channel in the new frequency interval.
