摘要：
An apollonian shaped ultra-wideband circular monopole antenna based oil descartes circle theorem is presented. Different self similar geometries front DCT are analyzed and optmized for UWB applications. The proposed design is slightly modified to ensure all overall smooth current distribution limited by the Junction point nature of the fractal geometries. The experimental results are compared with conventional circular disk monopole (and annular monopole antenna. The measured return loss of the proposed design below - 10 dB is from 2.4 to over 40 GHz and its radiation pattern is omni-directional compared with circular disk and annular antennas in most of its impedance bandwidth. Moreover due to the fractal shape, the proposed design has less weight and wind loading effect. (c) 2008 Wiley Periodicals, Inc. Microwave Opt Technol Lett 50: 1605-1608, 2008.
