<p align="justify">Monopole antenna is the antenna that very popular and often be used. This antenna can be used for broadcasting applications, car radio, land mobile communication services and the newest for cellular telephones. Monopole antenna has an omni directional radiation pattern so that this antenna can also be used to detect the existence of object undergrounds with borehole technique. With the advance of antenna frequency will decreases the height of the antenna itself and at once increasing the propagation signal losses. If the antenna observed from economy and mobility aspects, the minimum height of antenna is better so that the electromagnetic signal that being radiated can penetrate some specific mediums and succeed being received by the receiver antenna.<p align="justify"><p>This project discusses the simulation and implementation of designing monopole antenna with 1 GHz frequency which can be used for the utility of Ground Penetrating Radar (GPR) with borehole technique. This monopole antenna is very simple and easy to be made with good precision and the implementation and measurements referring the same result with the simulations. The antenna is tested, simulated and compared using GPRMAX 2D/3D software for two GPR techniques which are surface GPR and borehole GPR. The targeted objects that be detected are the ball made from conductor and rubber.<p align="justify"><p>This project also discusses and compares the superiority of monopole antenna to dipole antenna in imaging the object undergrounds with using the borehole GPR technique.<p align="justify"><p>The result of this research proves that the GPR method with borehole technique is able to detect the objects which have a spherical form and located inside the sand with material made from conductor and rubber with enough accurate results. <br />
