Abstract
Antenna systems for electronic devices, such as radiotelephones, include a paging antenna that enhances paging mode operation when a pivotable primary antenna is in a stored position. Paging antennas are disposed within a hinge rotatably secured to one end of a radiotelephone housing. A primary antenna, in electrical communication with the transceiver, is secured to the hinge and rotatable therewith along a predetermined path of rotation from a stored position adjacent the housing to an operating position extending away from the housing. Radiation axes for a primary antenna and a paging antenna are orthogonal.
