Abstract
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.
