Estimating the term…
Wireless portable electronic devices such as laptop computers are provided with antennas and radio-frequency transceiver circuitry. Antenna structures and transceiver circuitry may be provided within a clutch barrel in a laptop computer. The clutch barrel may have a dielectric cover. Antenna elements may be mounted within the clutch barrel cover on an antenna support structure. The antenna support structure may be mounted to a metal housing frame. The metal housing frame may have a tab-shaped extension that serves as a heat sink. The heat sink may draw heat away from the transceiver circuitry. The transceiver circuitry may be coupled to the antenna using a radio-frequency transmission line path that contains microstrip transmission lines or coaxial cable transmission lines. The transceiver circuitry may be coupled to logic circuitry on a laptop computer motherboard using a digital data communications path.
A portable wireless electronic device, comprising:
Clutch barrel structures located in a clutch barrel between an upper and lower housing portion of a portable electronic device, comprising:
The clutch barrel structures defined in claim further comprising a frame member heat sink next to the shielding can to draw heat away from the transceiver circuitry.
The clutch barrel structures defined in claim wherein the frame member heat sink is formed from part of a metal frame that is mounted to a portable computer housing cover.
The clutch barrel structures defined in claim wherein the antenna structures comprise at least two flex circuit antenna elements mounted to a dielectric antenna support structure.
The clutch barrel structures defined in claim further comprising a metal heat sink extension to a metal housing frame, wherein the metal heat sink extension is adjacent to the transceiver circuitry and wherein the antenna structures comprise a dielectric antenna support structure that is mounted to the metal housing frame.
Structures in a portable computer that has an upper housing portion, a lower housing portion, and a portable computer clutch barrel associated with a hinge that connects the upper housing portion to the lower housing portion, comprising:
