A novel ultra‐wide band printed slot antenna is presented. By using the novel feeding structure of a circular patch with a tapered microstrip line, the bandwidth of the elliptical slot antenna is greatly enhanced. The impedance bandwidth (VSWR < 2) reaches 174%, covering 1.90–27.7 GHz with bandwidth ratio of 14.6:1. This novel structure also features a bidirectional radiation pattern and a thin profile, making it promising in various wideband applications. © 2008 Wiley Periodicals, Inc.
