ULTRA-WIDE-BAND ANTENNA HAVING QUARTER-CIRCULAR-SLOT AND METHOD FOR MANUFACTURING THE SAME

摘要

PURPOSE: An ultra wideband antenna and a manufacturing method thereof are provided to manufacture an subminiature antenna while satisfying the ultra wideband frequency band by using the symmetry plane of the antenna with symmetrical round shaped structure and a PMW(Perfect Magnetic Wall) of the symmetry plane. CONSTITUTION: An ellipse shaped slot is arranged in a ground(22). A circular patch which has smaller radius than the slot(21) in the other side of a substrate is asymmetrically arranged with the slot. The frequency band of an ultra wideband is obtained in order to have a gap between the patch and the slot when the patch is formed in the end terminal of a tapered feeder(23). A first open side is formed by vertically cutting a symmetry plane by centering a vertical directional PMW of the ellipse shaped slot. A semicircular shape patch(24) is formed by dividing the circular patch into two equal parts.
