| 1. A multi-band antenna using a whip having an independent power feeding function in a wireless telecommunication terminal,
comprising:
a first feed point for feeding an electric signal provided from an electric signal providing means;
a second feed point for feeding an electric signal provided from the electric signal providing means;
a plurality of radiating means for radiating the electric signal fed from the first feed point in a form of an electromagnetic
wave signal; and
a whip radiating means for radiating the electric signal fed from the second feed point in a form of an electromagnetic wave
signal in order to increase the radiant efficiency of the electromagnetic wave signal radiated from the radiating means and
extend a bandwidth when the whip radiating means is drawn out of the wireless telecommunication terminal,
wherein the second feed point feeds by receiving the electric signal through a separate second transmission line diverged
from a first transmission line providing the electric signal from the electric signal providing means to the first feed point.
