Abstract

This article presents an elliptical shaped slot ultra-wideband antenna with high gain (10.3 dBi) and compact size (107.7x68 mm(2)) that designed and improved by four steps. Also, it can perform in an impedance bandwidth (IBW) from 0.98GHz to 4.5GHz that is satisfactory IBW for ground penetrating radar (GPR) application. The proposed antenna is fabricated for experimental testing and getting GPR images in a sandbox. Simulation and measured results ensure a desirable GPR antenna.
