A simple square‐slot antenna capable of providing a very wide impedance bandwidth of larger than 9 GHz is presented. The ultra‐wideband operation for the proposed antenna is realized by using a novel feeding mechanism of loading an offset rectangular stub at the end of the microstrip feed line. With the proper offset distance of rectangular stub chosen, the proposed antenna can operate in the 2.78–12.02‐GHz frequency range and covers the UWB operating bandwidth of 3.1–10.6 GHz. The antenna radiation patterns at 3, 5.3, 7.9, and 10 GHz are also presented. © 2006 Wiley Periodicals, Inc.
