Abstract
The present invention is a spring-loaded manually extendable antenna for a mobile phone. An antenna extension system includes an extendable antenna stowed within an antenna housing. Within the antenna housing is a compressible spring. Attached to the bottom end of the antenna is a washer. The antenna is held in a stowed position by a manual release mechanism. When a mobile phone user desires, the manual release mechanism is depressed, which allows the antenna to be manually driven upward by the spring. The antenna is then extended to the extended position.
