Electronic device with isolated cavity antennas
First Claim
1. A portable computer, comprising:
- a housing having an upper metal housing that contains a display and having a lower metal housing that contains a keyboard;
hinges that connect the upper metal housing to the lower metal housing, wherein the upper metal housing rotates relative to the lower metal housing about a rotational axis between a closed position and an open position; and
an antenna mounted entirely between opposing upper and lower portions of the lower metal housing and between the hinges, wherein the upper metal housing has a rear metal portion that is separated from the lower metal housing by a first slot when the upper metal housing is in the closed position and that is separated from the lower metal housing by second and third slots when the upper metal housing is in the open position and wherein the antenna transmits and receives antenna signals through the first, second, and third slots.

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.
