摘要：
A compact printed ultra-wideband (UWB, 3.1-10.6 GHz) circular-slot antenna with a notched frequency, band at 5 GHz is presented. The antenna is a uniplanar structure and occupies a compact area of 25 x 26 mm(2) only, (the side length is less than 27% of the lower edge frequency at 3.1 GHz). The antenna has a U-slotted circular stub embedded inside the circular slot. By choosing the length of the U-slot cut in the circular stub to be about a half-wavelength of the desired notched frequency, band-notched UWB operation is obtained. (c) 2005 Wiley Periodicals, Inc.
