Abstract: A wireless terminal antenna is disclosed. The antenna includes a pull rod, a pull rod pedestal located at the base of the pull rod, and a spiral coil. One end of the spiral coil is electrically connected with the pull rod pedestal. The pull rod is axially retractable along the pull rod pedestal until it is retracted into the space enclosed by the spiral coil. At idle time, the pull rod is nested inside the spiral coil so that it is short and portable. When receiving signals normally, the pull rod can be pulled out. The antenna is miniaturized, portable, and provides good performance.
