1. A mobile telephone comprising:
- an antenna body for transmitting and receiving radio waves;
a terminal for performing communication based on the radio waves transmitted and received by the antenna body; and
a means for maintaining the antenna body to be higher by a predetermined height than the terminal;
wherein the antenna body comprises;
a cylindrical or circular column-type dielectric substance; and
an antenna conductor including a radiation section for radiating the radio waves, formed by at least two radiation portions of approximately equal length along the longitudinal surface of the cylindrical dielectric substance, and respective impedance matching sections formed on the top and bottom surfaces of the dielectric substance, a first respective impedance matching section connected to one end of a first radiation portion and a second respective impedance matching section connected to one end of a second radiation portion of said at least two radiation portions, wherein a total length of said at least two radiation portions is equal to λ
/2 wavelength;
wherein another end of each of the first radiation portion and second radiation portion are arranged adjacent each other so as to facilitate connection to the terminal; and
wherein the antenna body is fixed to be higher than the terminal by the predetermined height when the mobile telephone is in use.

Abstract
An antenna for a mobile telephone, in which a radiation source of the antenna is separated from the user'"'"'s head while the mobile telephone is in use, to prevent an influence of the radiation waves on the user'"'"'s head and prevent the non-directional property of the radiation pattern from being degraded. The mobile telephone comprises an antenna body for transmitting and receiving radio waves; a terminal for performing communication based on the radio waves transmitted and received by the antenna body; and a support for maintaining (or supporting) the antenna body to be higher by a predetermined height than the terminal, when the mobile telephone is in use.

13. An antenna for use in a mobile telephone, comprising:
-
an antenna body of said antenna including;
a cylindrical or circular column-type dielectric;
an antenna conductor including a radiation section for radiating the radio waves, formed on the longitudinal surface of the dielectric substance, and impedance matching sections formed on the top and bottom surfaces of the dielectric substance; and
,wherein the antenna body has a specific length such that transmission and reception waves resonate with the half wavelength (λ
/2), and the radiation section is formed at the center of the antenna body and is fixed in a longitudinal direction of the dielectric substance.
