This data set contains list of figure that describe an antenna geometry which has been designed for UWB applications. Further the graphical results that are obtained from simulations as well as practical measurement of the fabricated prototype has also been included for reference. The research objective is to design an UWB antenna with band rejection capability by employing slotted resonator and EBG unit cells. The simulated data is obtained by using commercially available FEM based Electromagnetic solver called as HFSS. The measured data is obtained using vector network analyzer (VNA).
