Abstract
The present invention relates to a folded monopole intenna which is installed in an upper portion of a back surface in the interior of a wireless instrument. There is provided a folded monopole intenna which is formed of a conductive metal material and is formed of a feeding point structure which goes in an upper direction for thereby forming a value L in order for a pattern of an intenna to become a direct medium with respect to a signal transmission and receiving operation of a wireless instrument and an offset point structure which is provided near the feeding point structure in parallel for thereby forming a value C, whereby the value L by the feeding point structure and the value C of the offset point structure are offset each other, for thereby decreasing an impedance to a metal itself resistance level.
Description
FOLDED MONOPOLE INTENNA
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a folded monopole intenna capable of
transmitting and receiving a radio signal by supporting a folded monopole intenna,
and in particular to a folded monopole intenna which is capable of significantly
enhancing a transmission and receipt quality of a radio signal by implementing an
intenna pattern formed of a feeding point structure which goes in an upward
direction for forming a value L and an offset point structure which is positioned
near the feeding point structure in parallel for thereby forming a value C and by
decreasing an impedance of an intenna to a metal itself resistance level.
2. Description of the Background Art
A generally, an intenna is referred to as a built-in type antenna and is
directed to an apparatus which is engaged in the interior of a wireless instrument
and has a slim structure by decreasing the entire volume of a wireless instrument
differently from an antenna which is provided in an outer portion of a wireless
instrument.
However, a conventional intenna is not developed to be mounted in a
wireless instrument which is designed to be slim like a cellular phone. In particular,
there is not an intenna which is developed for the use in a CDMA frequency
method or a PCS frequency method. Therefore, the intenna is recognized as a
certain obstacle in a development of a small size cellular phone.
SUMMARY OF THE INVENTION
Accordingly, it is an object of the present invention to provide a folded
monopole intenna which overcomes the problems encountered in the conventional
art.
It is another object of the present invention to provide a folded monopole
intenna which is capable of decreasing an impedance to a metal itself resistance
level and significantly enhancing a transmission and receiving quality of a radio
signal in such a manner that an intenna pattern is formed of a feeding point
structure which is provided in the interior of a cellular phone body and goes in an
upward direction for thereby forming a value L and an offset point structure which
is provided near the feeding point structure in parallel and forms a value C.
To achieve the above objects, in an intenna which is installed in an upper
portion of a back surface in the interior of a wireless instrument, there is provided a
folded monopole intenna which is formed of a conductive metal material and is
formed of a feeding point structure which goes in an upper direction for thereby
forming a value L in order for a pattern of an intenna to become a direct medium
with respect to a signal transmission and receiving operation of a wireless
instrument and an offset point structure which is provided near the feeding point
structure in parallel for thereby forming a value C, whereby the value L by the
feeding point structure and the value C of the offset point structure are offset each
other, for thereby decreasing an impedance to a metal itself resistance level.
In addition, in the intenna pattern, the feeding point structure and the offset
point structure are the same one body in which a linear shape having a certain
thickness is continuously formed and is bent by a certain times.
In another pattern of the intenna, the feeding point structure and the offset
point structure are the same one body in which a linear shape having a certain
thickness is continuously formed and is bent by a certain times and at the same
time said intenna pattern includes a divided pattern shape which is divided in a
certain direction by a certain length at a certain position of the formed pattern.
