摘要
A Printed ultra-wideband (UWB, 3.1-10.6 GHz) quasidipole antenna with the band-notched characteristic is presented. The antenna mainly comprises two radiating elements: an tipper semi-circular disk and a lower semi-circular disk embedded with a pair of narrow slits, whose length is about one quarter-wavelength at the desired notched frequency. Both the tipper (aid lower semi-circular disks are of the same dimensions, thus making the proposed antenna tend to be a dipole structure. With a compact size of 25 X 25 mm(2), the proposed antenna showing UWB operation with a notched frequency v band at 5 GHz is demonstrated. (c) 2006 Wiley Periodicals, Inc.
