Ultra wideband internal antenna

#The present application is based on, and claims priority from, Korean Application Number 2004-0093011, filed Nov. 15, 2004, the disclosure of which is incorporated by reference herein in its entirety.

#1. Field of the Invention

#The present invention relates generally to an antenna provided in a mobile communication terminal to transmit and receive radio signals and, more particularly, to an ultra wideband internal antenna, which is provided within a mobile communication terminal and is capable of cutting off frequencies in a specific frequency band while processing ultra wideband signals.

#The above and other objects, features and other advantages of the present invention will be more clearly understood from the following detailed description taken in conjunction with the accompanying drawings, in which:

#FIG. 1 is a view showing the construction of a typical Planar Inverted F Antenna (PIFA);

#FIG. 2 is a view showing the construction of a conventional ultra wideband antenna;

#Preferred embodiments of the present invention are described with reference to the attached drawings below. Reference now should be made to the drawings, in which the same reference numerals are used throughout the different drawings to designate the same or similar components. In the following description of the present invention, detailed descriptions may be omitted if it is determined that the detailed descriptions of related well-known functions and construction may make the gist of the present invention unclear.

#FIG. 3 is a view showing the construction of an ultra wideband internal antenna according to a first embodiment of the present invention.

#Referring to FIG. 3, an ultra wideband internal antenna 30 according to a first embodiment of the present invention is formed on a top surface of a dielectric substrate, and includes a first radiation part 31, a second radiation part 32, a feeding part 33 and ground parts 34.
