Abstract
An electronic device such as a laptop computer may have an upper housing and a lower housing. The lower housing may have a clutch barrel coupled to the upper housing by a hinge. The upper housing may be rotatable relative to the lower housing between an open position and a closed position. The upper housing may have a curved metal surface facing the clutch barrel. The device may have an antenna with a radiating arm on a curved interior surface of a substrate in the clutch barrel. The radiating arm may extend parallel to the curved metal surface. The radiating arm may remain separated from the curved metal surface across its lateral area as the upper housing is rotated from the open position to the closed position. This may ensure that the antenna is provided with a uniform capacitive load from the upper housing at all upper housing positions.
