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.
