Design Of UWB Bow Tie Antenna For GPR Object Detection

Abstract

Ground penetrating radar (GPR) being an ultrawide band (UWB) radar system, antenna plays a vital role in optimizing its RF transceiver performance. Bowtie antenna is very popularly used in GPR applications as it can satisfy the stringent requirements of a UWB antenna. This paper presents the design of a UWB bow-tie antenna satisfying wide band width of 450MHz to 2.3GHz without dissipative loading. The simulation has been carried out in HFSS v17, and the antenna has been fabricated and tested to verify the desired performance. The proposed antenna can be used for the UWB GPR system for the detection of buried objects.
