One pin is applied in order to expand the impedance bandwidth. Two other pins are utilized to miniaturize the size of patch as well. The measured impedance bandwidth ( $$\text{ VSWR}\le 2$$ ) of the fabricated antenna is more than 90% in the frequency range 3.92-10.67GHz for ultra-wideband (UWB) applications. The antenna size is $$0.438\lambda _{0}\times 0.365\lambda _{0}\times 0.170\lambda _{0}$$ at its center operating frequency. Also, radiation patterns with acceptable stability within the bandwidth are obtained. In addition, the effects of some key parameters are investigated to describe the performance of the proposed design.
