“…The Ground Penetrating Radar (GPR) system consists of two antennas, with one functioning as the transmitting antenna responsible for emitting electromagnetic waves. Meanwhile, the other antenna serves as the receiving component, capable of operating independently or concurrently with the transmitting antenna [2] Transmitting antennas generate electromagnetic waves, directing them towards objects concealed in the ground or behind walls [3]. The speed of the wave is linked to the dielectric constant of the medium.…”

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.

In this research, a microstrip antenna with a bowtie hole was constructed. The proposed antenna is designed and fabricated to operate in the 2.4 GHz frequency band. Arc antennas are a popular choice due to their flat structure, lightweight design, wide bandwidth, and high gain characteristics for GPR applications. The antenna was designed as a microstrip antenna in the size of 58 mm x 69 mm. using an FR4 duplex printed circuit board with a material thickness of 1.6 mm, a dielectric constant of 4.3 and a transverse dielectric loss tangent of 0.02. The design and simulation were performed using CST Studio Suite programming. The results of the simulation and measurements antenna were tested for resonant frequency, return loss, VSWR, bandwidth, impedance, and polarization, and the simulation results were compared. The measurements carried out with a Vector Network Analyzer, showed a return loss of -18, a VSWR of 1.29, a bandwidth of 100 MHz, an impedance of 47 ohms, and a high gain of 18 dB at 2.42 GHz. Both the simulation and measurement results demonstrated good agreement, with frequency bands of interest that were very close and stable with high-gain omnidirectional radiation characteristics. Thus, the antenna is well-suited to meet the requirements of GPR applications.

In this paper, a structure of a patch antenna operating at 0.5 GHz is proposed for ground-penetrating radar (GPR) applications, with an optimized performance at low frequencies. The structure was designed using FR4 substrate, with a 4.4 permittivity value, and a tangent loss equivalent to 0.021. The prototype design is backed by an optimized rectangular reflector, which has improved the antenna gain and directivity. The performance of the antenna is evaluated in terms of the return loss, gain, and the radiation pattern for two cases, with and without a reflector. When using the reflector, a good radiation pattern is obtained, a wide operational bandwidth ranging from 0.4GHz and 1.25 GHz is achieved, and an increased gain from 4.3 to 7.43dB was realized.
