This letter presents a rectangular slot antenna with a novel coplanar waveguide fed diamond patch covering frequency range from 2.27 to 10.63 GHz based on S 11 < −10 dB, 129%. The fabricated antenna has a small size as high as 42 × 42 mm 2 . The measured results are in good agreement with simulation results. The measured radiation patterns are nearly omni‐directional over the most of the frequency bandwidth. The antenna gain ranges from 1.6 to 7.6 dBi. The simple structure, compact size, and good characteristics make the antenna easy to use in commercial ultra wideband systems. © 2009 Wiley Periodicals, Inc.
