Abstract A novel ultra‐wideband (UWB) printed monopole microstrip patch antenna is presented. The UWB is provided by using unequal V‐shaped slot arms to provide staggered resonance frequencies from different couplings. Second, using modified ground plane to enhance the bandwidth. An impedance bandwidth from 2 to 30 GHz is obtained using HFSS® with discontinuities in this bandwidth. For further enhancement in the bandwidth, antenna gain as well as removing the harmonic frequencies, the embedded electromagnetic band‐gap (EBG) structure is used. The impedance bandwidth reaches 2000%, covering the frequency range 0.5–40 GHz with bandwidth ratio of 80:1. Three different techniques of metamaterial are used, namely using embedded square shapes as artificial magnetic conductor, using embedded uniplanar square EBG structure without via, and, finally, using embedded metallo‐electromagnetic band‐gap structure with via. © 2010 Wiley Periodicals, Inc.
