  • Method and apparatus for detecting physical position of a retractable antenna
    Patent number: 6486835
    Abstract: Disclosed is a method and apparatus for use in a wireless terminal for detecting a position of a retractable antenna relative to a fixed antenna. The method has steps of positioning an electrical contact for being electrically coupled to the retractable antenna only when the retractable antenna is retracted within a body of the wireless terminal, and at least partially contained within the fixed antenna; detecting a presence of RF energy that is coupled into the retractable antenna from the fixed antenna, wherein the detected presence of the RF energy is indicative of the retractable antenna being in the retracted position; and, if the retractable antenna is not indicated to be in the retracted position, transmitting RF energy from the retractable antenna using more RF power than if the retractable antenna were indicated to be in the retracted position.
