Title:
RETRACTABLE AND PIVOTABLE MULTIPLE FREQUENCY BAND ANTENNA
Document Type and Number:
WIPO Patent Application WO2000010223
Kind Code:
A9
Abstract:
A pivotable and retractable antenna contains mechanical and electrical components for connecting to, and matching the impedance of, radio frequency circuitry within an electronic device, such as a radiotelephone. A dielectric substrate has one end movably mounted to the housing of a radiotelephone and an opposite free end. The end movably mounted to the housing is configured to move into various positions to allow the dielectric substrate to have a first extended position, a second extended position and a retracted position. In a first extended position, the dielectric substrate extends along a longitudinal direction defined by the radiotelephone housing. In a second extended position, the dielectric substrate free end is pivoted away from the radiotelephone in a direction transverse to the longitudinal direction of the housing.
