Over the past few years, remote sensing, radar, and imaging applications have all utilized Ultra-Wideband (UWB) technology. This work provides a parametric study on monopole antennas for Ground Penetrating Radar (GPR) systems. The intended antenna has an incomplete ground plane and two circular radiating patches, known for their compact design, notable high gain, and high efficiency. Furthermore, it provides an advantageous bandwidth. The suggested antenna design show-cases its appropriateness for lower frequencies, attributed to its compact dimensions. The proposed design for antenna characteristics in ground-penetrating radar systems emphasizes a requirement for large bandwidth and high gain to achieve optimal image resolution. This article delineates the design methodology and simulation of a monopole antenna developed specifically for applications in Ground Penetrating Radar (GPR). In this design, we utilize the Roger RT Duroid 5880 substrate, characterized by a relative permittivity of 2.2, a height (h) of 1.575 mm, and a loss tangent of 0.0009. The dimensions of the substrate are miniaturized to 42 mm  40 mm  1.575 mm. The antenna results are obtained using CST computer simulation technology software to derive the results for this antenna, and the simulations yielded favorable outcomes. The proposed array antenna demonstrates commendable characteristics at an operating frequency of 5.6 GHz, with a reflection coefficient (S11) of -46 dB, a bandwidth of 1.6 GHz, a gain of 8.302 dB, VSWR of 1.009, and an efficiency of 99.9 %. The obtained results are highly competitive, suggesting that the proposed antenna is well-positioned to fulfill the requirements associated with Ground Penetrating Radar (GPR) applications.
