A coplanar‐waveguide fed ultra‐wideband (UWB) antenna with substrate‐integrated waveguide (SIW) stop‐band resonators is introduced for the 3–10 GHz band. The symmetrically placed SIW cavities provide dual‐stop‐band characteristics due to their TE 101 and TE 102 resonance modes. Thus, the entire UWB is divided into three pass‐bands which cover the frequency ranges 4.23–4.62 GHz, 6.6–8.175 GHz, and 9.39–10.7 GHz. Measurements of a prototype show good agreement with simulation results with a minimum measured return loss of 9 dB in any of the three pass‐bands. © 2014 Wiley Periodicals, Inc.
