The antenna has a simple design which is composed by a rhombus-shaped patch and a modified ground plane. The working bandwidth is improved by removing the metal from the upper part of the ground plane surrounding the patch and by introducing a corrugation geometry in the ground plane. The proposed antenna was designed on a low-cost FR4-substrate having a compact size of 0.2721&lambda;₀&times;0.2093&lambda;₀&times;0.0157&lambda;₀at 3.14 GHz. All the simulations were carried out by using the commercially software CST Microwave Studio^TM. The simulated results show that the designed antenna covers an UWB extending from 3.14 GHz to 13.82 GHz (125.94%) and indicate excellent radiation performances throughout the operating bandwidth. The measured bandwidth is nearly extending between 3.95 GHz and 13.92 GHz (111.58%). Besides, the antenna bandwidth response was checked in close proximity to a mass of Concrete. The obtained results are satisfactory and assure the efficiency of the designed antenna to work as a GPR antenna.</span></span></span></div> Ultra Wideband (UWB) Antenna, Rhombus-Shaped Antenna, Ground Penetrating Radar (GPR). 2041 2041 http://ijeee.iust.ac.ir/browse.php?a_code=A-10-3648-1&slc_lang=en&sid=1 A.
