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.
Highlights
The research interest on ultra-wideband (UWB) systems has gained popularity mainly after the year 2002 when the US department of Federal Communications Commission (FCC) allocated a license-free spectrum for Industrial and Scientific purposes
Ultra-wideband antenna designs that are suitable for ground penetrating radar applications mainly require greater frequency bandwidth along with the parameter of high gain
It can be observed that the bow-tie antenna designed by cutting edges has sufficient percentage bandwidth, which is suitable for an UWB Ground Penetrating Radar (GPR) system
Summary
The research interest on ultra-wideband (UWB) systems has gained popularity mainly after the year 2002 when the US department of Federal Communications Commission (FCC) allocated a license-free spectrum for Industrial and Scientific purposes. This greater step of FCC has opened new doors of researches for UWB in the field of wireless communications and microwave imaging [1], [2]. This paper examines the technical and methodological aspects involved during the design of ultra-wideband antennas for ground penetrating radar detection applications. The organization of this paper is as follows: Section II discusses the UWB antenna designs and methodologies suitable for GPR application.
