Electronic device with isolated cavity antennas
First Claim
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 and the lower housing portion has opposing first and second conductive surfaces;
first and second hinges 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, the antenna traces are shorted to the first conductive surface of the lower housing portion through a first conductive structure that contacts the first conductive surface, and the antenna traces are shorted to the second conductive surface of the lower housing portion through a second conductive structure that contacts the second conductive surface.

Abstract
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.
