<P>PROBLEM TO BE SOLVED: To provide a micro antenna exhibiting a multiple frequency band and broadband characteristics using a fractal radiation element which has a fractal grid structure of a specific pattern. <P>SOLUTION: The multi-resonant broadband antenna is configured in which a specific fractal antenna pattern is arranged, thereby making maximal an antenna area per unit area, improving antenna radiation efficiency and embodying an antenna small-sided in comparison with a frequency length. The antenna element includes a feed line which is adhered on the upper surface of a dielectric substrate and feeds the fractal radiation element, and a ground positioned on a lower surface of the dielectric substrate in accordance with the feed line. <P>COPYRIGHT: (C)2009,JPO&INPIT |
