Abstract
A multi-frequency internal antenna apparatus ( ) for a clamshell type electronic device includes a flexible circuit ( ) that electrically couples circuitry between the main housing ( ) and flip housing ( ). A conductive element ( ) is disposed on the main housing ( ) and tuned to be electrically resonant above the operating frequencies of the electronic device. The conductive element ( ) is disposed in proximity to the flip housing ( ) in the open position and is electrically coupled at a high impedance point to the flexible circuit ( ) and subsequently to the circuitry in the flip housing. When the movable flip housing is in the open position and being held by a user, the circuitry in the movable flip housing forms a secondary conductive element providing dipole characteristics that tunes the combined conductive elements to the operating frequencies of the electronic device.
