Electronic device with dual clutch barrel cavity antennas
First Claim
1. A portable computer, comprising:
- a housing having an upper housing portion that contains a display and having a lower housing portion;
hinges that connect the upper housing portion to the lower housing portion; and
first and second cavity antennas located between the hinges, wherein the upper housing rotates relative to the lower housing about a rotational axis, the upper housing has a dielectric portion adjacent to the rotational axis, the dielectric portion enlarges a gap between a portion of the lower housing and an opposing metal portion of the upper housing, and the first and second cavity antennas handle wireless antenna signals that pass through the gap.

Abstract
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.
