Abstract
An electronic device housing may have a base unit and a lid. Aligned antenna windows may be formed on opposing upper and lower surfaces of the base unit along a hinge. Antenna structures that are located between respective upper and lower antenna windows on the upper and lower surfaces may be based on a pair of antennas that are coupled to switching circuitry that can select which antenna to switch into use or may be based on an antenna having a position that may be adjusted relative to the upper and lower antenna windows using a mechanical coupling to the lid or using a positioner. A sensor such as a lid position sensor may monitor how the lid is positioned relative to the base unit. Information from the lid position sensor may be used in adjusting the antenna structures to optimize performance.
