“…Various feeding techniques are also discussed in [6] other than proposing a new feeding technique. In order to realize the new technique, the waveguide of the antenna is fixed and a screw is added on the opposite side of the feeder to increase the gain.…”

“…While other designed antennas seemed to target penetration depth as their operating bandwidth lies within the lower frequency band. The horn antenna designed in [6] has the least percentage of bandwidth even though its gain value is significantly higher due to which it can penetrates up to few feet under the ground. Nevertheless, a horn antenna design is still one of the best suitable candidates for GPR applications because of its highly directional properties, suitable gain, proper impedance bandwidth and less susceptibility to ground effect the performance of antenna.…”

“…In addition, GPR is also used in remote sensing techniques such as nondestructive testing of concrete and detection of trapped people underdebris or in opaque environment [6]. For the implementation of UWB GPR systems, the performance of various antenna designs, such as bow-tie antenna [7], [8], spiral antenna [7], loaded dipole antenna [9], TEM horn antenna [10], [11], tapered slot antenna [12], [13] and Vivaldi antenna [14], [15] have been evaluated.…”

Abstract-This paper presents a comparative review study on ultra-wideband (UWB) antenna technology for Ground Penetrating Radar (GPR) applications. The proposed antenna designs for UWB ground penetrating radar include a bow-tie antennas, Vivaldi antennas, horn antennas, planar antennas, tapered slot antennas, dipole antennas, and spiral antennas. Furthermore a comprehensive study in terms of operating frequency range, gain and impedance bandwidth on each antenna is performed in order to select a suitable antenna structure to analyze it for GPR systems. Based on the design comparison, the antenna with a significant gain and enhanced bandwidth has been selected for future perspective to examine the penetration depth and resolution imaging, simultaneously suitable for GPR detection applications. Three different types of antennas are chosen to be more suitable from the final comparison which includes Vivaldi, horn and tapered slot antennas. On further analysis a tapered slot antenna is a promising candidate as it has the ability to address the problems such as penetration depth and resolution imaging in GPR system due to its directional property, high gain and greater bandwidth operation, both in the lower and higher frequency range.

“…GPR have a number of applications in the field of engineering for military and civilian applications like the detection of landmines, through-wall imaging, in remote sensing techniques such as non-destructive testing of concrete and detection of trapped people under debris or in the opaque environment [5][6]. For the implementation of UWB technology specifically in the applications of GPR different types of antenna like a horn, bow tie, tapered slot, patch, spiral, and dipole antennas have been designed previously.…”

Abstract. The aim of this paper is to present a monostatic arc-shaped ultra-wideband (UWB) printed monopole antenna system with 3-16 GHz frequency bandwidth suitable for through-wall detection. Ground penetrating radar (GPR) technique is used for detection with the gain of 6.2 dB achieved for the proposed antenna using defected ground structure (DGS) method. To serve the purpose, a simulation experiment of through-wall detection model is constructed which consists of a monostatic antenna act as transmitter and receiver, concrete wall and human skin model. The time domain reflection of obtained result is then analysed for target detection.
