Electronic Device With Dual Clutch Barrel Cavity Antennas

摘要

An electronic device has antennas formed from cavity antenna structures. The electronic device may have a metal housing. The metal housing may have an upper housing in which a component such as a display is mounted and a lower housing in which a component such as a keyboard is mounted. Hinges may be used to mount the upper housing to the lower housing for rotation about a rotational axis. Cavity antennas may be formed in a clutch barrel region located between the hinges and running along the rotational axis. A flexible printed circuit may be formed between the cavity antennas. Each cavity antenna may have a first end that is adjacent to one of the hinges and a second end that is adjacent to the flexible printed circuit. Cavity walls for the cavity antennas may be formed from metal housing structures such as metal portions of the lower housing.

主权项

1. A portable computer, comprising:
a housing having an upper housing portion that contains a display and having a lower housing portion that contains a keyboard; hinges that connect the upper housing portion to the lower housing portion so that the upper housing portion rotates relative to the lower housing portion about a rotational axis between a closed position and an open position, wherein there is a gap between opposing metal portions of the upper and lower housing portions; and an antenna in the lower housing portion between the hinges that transmits and receives antenna signals through the gap.
