Electronic Device with Isolated Cavity Antennas

摘要

An 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. A slot-shaped opening may separate the upper and lower housing. A flexible printed circuit with ground traces may bisect the slot-shaped opening to form first and second slots. Cavity antennas may be aligned with the slots. Each cavity antenna may include a hollow carrier with a pair of speakers. The speakers may have ports that emit sound through aligned openings in the lower housing. Conductive gaskets surrounding the ports may acoustically seal the speaker ports while shorting the cavity antenna to the lower housing.

主权项

1. A portable computer, comprising:
a metal housing having an upper housing portion that contains a display and having a lower housing portion, wherein the upper and lower housing portions are separated by a slot-shaped opening; first and second hinges at opposing ends of the slot-shaped opening that connect the upper housing portion to the lower housing portion; and at least one cavity antenna in the lower housing portion that is aligned with at least a portion of the slot-shaped opening, wherein the cavity antenna includes antenna traces on a dielectric support structure.
