A printed wide-slot antenna for portable ultrawideband application is presented in this article. It consists of a staircase-shape patch and an arc-shape slot etched on different sides of a thin microwave substrate. By using a microstrip feedline with matching stubs to excite the patch and placing a thin conductor-backed ab sorber under the slot, wide impedance bandwidth (SWR <2) of 132.8% and broadside radiation patterns are obtained. This antenna has a peak gain and an average gain of 4.7 and 3.7 dBi, respectively. Moreover, it has a low profile of 0.18λ, where λ is the free space wavelength referring to the center frequency of the operating bandwidth. The antenna is very suitable for the portable devices of nowadays UWB wireless communication systems. © 2007 Wiley Periodicals, Inc.
