摘要： An antenna system for an electronic device enables the device to communicate via numerous wireless communication protocols, such as wireless broadband communication protocols. The antenna is able to extend from the body of the electronic device in order to meet efficiency and specific absorption rate requirements, while retracting into the footprint of the device when not in use. The antenna is easily disassembled and reassembled from the device without the use of tools, and may automatically disassemble from the device in order to avoid sustaining damage or exposing a user to excessive electromagnetic radiation.

摘要： A portable electronic device is provided for sending and receiving a communication signal to and from a target, respectively. Among other components, the portable electronic device includes an antenna, a transceiver, a signal processing system and control circuitry. The signal processing system determines a distance between the target and the portable electronic device. There are various ways to determine the relative distance between the target and the device. One such methodology is to use a change in a signal that is transmitted from the transceiver and reflected from the target back to the transceiver. The change can be a frequency shift, a phase shift, a capacitive coupling change, an impedance change, or any other change which notes the presence of a target relative to the transceiver. The control circuitry may be used to change the amount of power applied to the antenna and/or to change at least one security measure of the device depending on the distance detected between the target and the device.
