Abstract
An electronic device may have an upper housing with a display and a lower housing with a keyboard. The upper housing may rotate between open and closed positions. The lower housing may include a first conductive wall separated from the upper housing by an upper slot and a second conductive wall separated from the upper housing by a lower slot. An antenna resonating element may be mounted within the lower housing and may convey signals in low and high frequency bands through the lower slot when the upper housing closed. The resonating element may be grounded to the second conductive wall and may be separated from a conductive cavity wall by at least one-sixteenth of a wavelength in the low frequency band. A parasitic element may be used to redirect signals in the low frequency band towards and through the upper slot when the upper housing open.
